📚 Summary of key learnings from Section 2, Part 2 of "The Complete JavaScript Course"

🔍 Topics: Strict Mode, Functions, Arrays, and Objects

1️⃣ 'use strict' Mode

'use strict';

• Enables strict mode in JavaScript.
• Helps catch common coding mistakes and "silent" errors.
• Enforces stricter parsing and error handling in your code.

✅ Use it at the beginning of your scripts or inside functions for safer code.

2️⃣ 🧠 Anonymous Functions

• Functions without names, stored in variables.

const greet = function () {
  console.log('Hello');
};

• Cannot be invoked before their declaration.
• Useful for short-term tasks and function expressions.

3️⃣ 🏹 Arrow Functions

• JavaScript’s version of lambda functions.

const sum = (a, b) => a + b;

• Shorter syntax than traditional functions.
• Do not bind their own this keyword (inherited from parent scope).
