Advanced JavaScript: ES6+ & Async Programming

Destructuring, spread/rest, Promises, async/await, and modules

✓

▼

Modern JavaScript — ES6+ Features

ES6+ (ECMAScript 2015 and beyond) transformed JavaScript into a modern, powerful language. These features are used in every professional JavaScript codebase.

// Destructuring — extract values cleanly
const user = { name: "Emeka", age: 17, school: "Zeeqtech" };
const { name, age } = user;  // Extract name and age

const scores = [90, 85, 92];
const [first, second] = scores;

// Spread operator — expand arrays/objects
const arr1 = [1, 2, 3];
const arr2 = [...arr1, 4, 5];  // [1,2,3,4,5]
const updatedUser = { ...user, age: 18 };  // Copy + update

// Promises — handle asynchronous operations
const fetchData = () => {
    return new Promise((resolve, reject) => {
        setTimeout(() => resolve("Data loaded!"), 1000);
    });
};

// Async/Await — cleaner way to handle Promises
const loadData = async () => {
    try {
        const result = await fetchData();
        console.log(result);  // "Data loaded!"
    } catch (error) {
        console.error("Error:", error);
    }
};
        

Fetch API — Making Real HTTP Requests

// Fetch data from a real API (using async/await)
const getCryptoPrice = async () => {
    const response = await fetch(
        'https://api.coingecko.com/api/v3/simple/price?ids=bitcoin&vs_currencies=ngn'
    );
    const data = await response.json();
    console.log(`Bitcoin price: ₦${data.bitcoin.ngn.toLocaleString()}`);
};
getCryptoPrice();
        

🚀 Why This Matters: Async programming is how every modern app works — fetching data from APIs, loading user profiles, submitting forms without page reloads. Understanding Promises and async/await is required for any frontend or backend JavaScript role.

💻 Project: Real-Time Data Dashboard
Build a web dashboard that:

Fetches live data from a free public API (e.g., Open Meteo for weather, CoinGecko for crypto, RestCountries for country data)
Displays the data in a clean, styled card layout
Has a search/filter function using JavaScript array methods
Updates automatically every 30 seconds with a live counter
Shows loading spinners during fetch and handles errors gracefully

Q1. What is the purpose of async/await in JavaScript?

✅ async/await is syntax sugar over Promises that makes asynchronous code look and behave like synchronous code — cleaner, more readable. await pauses execution of the function (not the browser) until the Promise resolves.

Q2. What does the spread operator (...) do in JavaScript?

✅ The spread operator (...) expands elements of an array or properties of an object. Common uses: copying arrays/objects, merging arrays, passing array items as function arguments.

SQL Databases — Designing & Querying Data

Relational databases, SQL queries, joins, and real-world data management

✓

▼

What is a Relational Database?

A relational database stores data in structured tables (like spreadsheets) with relationships between them. SQL (Structured Query Language) is used to create, read, update, and delete this data (CRUD operations).

Core SQL Commands

-- Create a table (DDL - Data Definition Language)
CREATE TABLE students (
    id        INTEGER PRIMARY KEY AUTOINCREMENT,
    name      TEXT NOT NULL,
    age       INTEGER,
    school    TEXT,
    created_at DATETIME DEFAULT CURRENT_TIMESTAMP
);

-- INSERT data (DML - Data Manipulation Language)
INSERT INTO students (name, age, school)
VALUES ('Emeka Okafor', 17, 'Zeeqtech High');

-- SELECT — query data
SELECT * FROM students;
SELECT name, age FROM students WHERE age >= 16;
SELECT * FROM students ORDER BY name ASC;

-- UPDATE and DELETE
UPDATE students SET age = 18 WHERE id = 1;
DELETE FROM students WHERE id = 5;

-- JOIN — combine tables
SELECT s.name, g.subject, g.score
FROM students s
JOIN grades g ON s.id = g.student_id;
        

NoSQL Databases

For unstructured or rapidly changing data, NoSQL databases like MongoDB (used by Flutterwave, most Nigerian fintechs) store data as JSON-like documents — more flexible but less structured than SQL.

🇳🇬 Databases in Nigerian Tech: Paystack uses PostgreSQL (SQL). Flutterwave uses MongoDB. Kuda uses both (SQL for transactions, NoSQL for user activity). Understanding both SQL and NoSQL makes you hireable at any Nigerian tech company!

Q1. What does SQL stand for?

✅ SQL stands for Structured Query Language — the standard language for managing and querying relational databases. Used with MySQL, PostgreSQL, SQLite, Microsoft SQL Server, and more.

Q2. What SQL command retrieves data from a table?

✅ SELECT retrieves data from tables. Basic syntax: SELECT columns FROM table WHERE condition ORDER BY column;. The most frequently used SQL command in any application.

Term 2: AI Projects, Fintech & Cybersecurity

Students build real AI projects with Python (scikit-learn, data visualisation), explore Nigeria's thriving fintech ecosystem, and learn cybersecurity fundamentals — ethical hacking concepts, OWASP security principles, and how to protect digital systems.

Build ML models with Python Analyse & visualise data Understand fintech systems Apply OWASP security Write secure code

Machine Learning with Python — Building Your First Model

Pandas, scikit-learn, and training a classification model

✓

▼

The Machine Learning Pipeline

Building any ML model follows the same process:

1. Collect & Load Data – CSV files, APIs, databases (use pandas)
2. Explore & Clean Data – Check for missing values, outliers, distributions
3. Feature Engineering – Select and transform input variables
4. Split Data – 80% training, 20% testing
5. Train the Model – Feed training data to the algorithm
6. Evaluate – Test on test data, measure accuracy/precision/recall
7. Improve & Deploy – Tune parameters, export, integrate into app

Hands-On: Building a Spam Classifier

# Install: pip install pandas scikit-learn
import pandas as pd
from sklearn.model_selection import train_test_split
from sklearn.feature_extraction.text import TfidfVectorizer
from sklearn.naive_bayes import MultinomialNB
from sklearn.metrics import accuracy_score

# Load dataset (SMS Spam Collection - free on Kaggle)
df = pd.read_csv('spam.csv', encoding='latin-1')[['v1','v2']]
df.columns = ['label', 'message']

# Prepare data
X = df['message']
y = (df['label'] == 'spam').astype(int)

X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2)

# Vectorise text to numbers
vectorizer = TfidfVectorizer()
X_train_v = vectorizer.fit_transform(X_train)
X_test_v = vectorizer.transform(X_test)

# Train model
model = MultinomialNB()
model.fit(X_train_v, y_train)

# Evaluate
predictions = model.predict(X_test_v)
print(f"Accuracy: {accuracy_score(y_test, predictions):.2%}")
        

🤖 Common ML Algorithms: Linear Regression (predict numbers), Logistic Regression (binary classification), Decision Trees (rule-based decisions), Random Forest (ensemble of trees — very powerful), Naive Bayes (text classification), K-Nearest Neighbors (similarity-based), Neural Networks (deep learning).

🤖 Project: Loan Approval Prediction
Download the "Loan Prediction Dataset" from Kaggle (free). Build a model that predicts whether a bank should approve a loan based on applicant data (income, credit history, etc.)

Use pandas to explore and clean the data
Handle missing values (df.fillna() or df.dropna())
Train a Random Forest classifier
Achieve >75% accuracy on the test set
Visualise feature importance using matplotlib

This is a real use case for Nigerian fintechs like Kuda, PalmPay, and carbon.ng!

Q1. What is the purpose of splitting data into training and test sets?

✅ Train/test split ensures you evaluate the model on unseen data. If you tested on training data, the model might just "remember" the answers without truly learning. A model that memorises training data but fails on new data is called overfitting.

Cybersecurity Fundamentals & Ethical Hacking Intro

OWASP Top 10, secure coding, common attacks, and digital defence

✓

▼

Why Cybersecurity Matters

Nigeria lost over ₦9.3 billion to cybercrime in 2023. Global cybersecurity jobs are expected to reach 3.5 million unfilled positions by 2025. Cybersecurity professionals earn among the highest salaries in tech — and every developer needs to write secure code.

The OWASP Top 10 — Most Common Vulnerabilities

1. Broken Access Control – Users accessing data they shouldn't (e.g., viewing another user's bank account)
2. Cryptographic Failures – Storing passwords as plain text, not using HTTPS
3. Injection Attacks – SQL Injection, XSS (Cross-Site Scripting): inserting malicious code into inputs
4. Insecure Design – Security not considered in architecture
5. Security Misconfiguration – Default passwords, open ports, verbose error messages
6. Vulnerable Dependencies – Using outdated npm packages with known vulnerabilities
7. Authentication Failures – Weak passwords, no MFA, session hijacking
8. Data Integrity Failures – Unvalidated data from untrusted sources
9. Logging Failures – Not detecting or logging suspicious activity
10. Server-Side Request Forgery (SSRF) – Server making requests to unintended locations

⚠️ Ethical Use Only: Cybersecurity knowledge must only be used ethically and legally — to defend systems you own or have explicit permission to test. Unauthorised access is a criminal offence under Nigeria's Cybercrime Act 2015. Ethical hackers (pentesters) always have written authorisation.

Secure Coding Practices

Never store passwords in plain text — use bcrypt hashing
Always validate and sanitise user input — never trust user data
Use HTTPS for all web communications
Keep dependencies updated — run npm audit regularly
Implement proper authentication and authorisation
Use parameterised queries to prevent SQL injection
Apply principle of least privilege — give minimum necessary access

Q1. What is a SQL Injection attack?

✅ SQL Injection is when an attacker inserts malicious SQL into a form field to manipulate the database — e.g., entering ' OR 1=1 -- as a username to bypass login. Prevented with parameterised queries.

Q2. What is the BEST way to store user passwords?

✅ Passwords should be hashed with bcrypt (or Argon2) — a one-way transformation that cannot be reversed. A "salt" adds random data to prevent rainbow table attacks. NEVER store plain text passwords. Every major data breach exposes plain-text passwords.

Payment Gateway APIs – Paystack/Flutterwave APIs that developers integrate to accept payments
POS Terminals – Connected to bank networks, used by agents in markets/shops
Open Banking – Future system where banks share data with 3rd-party apps (with user consent)

Integrating Paystack API (Code Preview)

// Paystack payment integration (JavaScript)
const makePayment = () => {
    const handler = PaystackPop.setup({
        key: 'pk_test_your_public_key',
        email: 'customer@email.com',
        amount: 5000 * 100,  // ₦5,000 in kobo
        currency: 'NGN',
        callback: (response) => {
            console.log('Payment success! Reference: ', response.reference);
            // Verify on your backend server
        }
    });
    handler.openIframe();
};
        

Q1. What makes Nigeria's fintech market particularly significant?

✅ Nigeria is Africa's largest fintech market because it combines: the continent's largest population, a significant unbanked population (creating demand for digital finance), strong tech talent, and a supportive startup ecosystem.
