JavaScript Assignment Operators 📝
Assignment operators assign values to variables. They can also modify values before assigning them.

1️⃣ List of Assignment Operators
Operator Example Equivalent To Description
= x = 5 x = 5 Assigns 5 to x.
+= x += 2 x = x + 2 Adds and assigns.
-= x -= 3 x = x - 3 Subtracts and assigns.
*= x *= 4 x = x * 4 Multiplies and assigns.
/= x /= 2 x = x / 2 Divides and assigns.
%= x %= 3 x = x % 3 Finds remainder and assigns.
**= x **= 2 x = x ** 2 Exponentiates and assigns.

2️⃣ Examples of Assignment Operators
✅ 1. Simple Assignment (=)
Assigns a value to a variable.

let a = 10;

console.log(a); // 10

✅ 2. Addition Assignment (+=)
Adds a value to the variable and assigns the result.

let b = 5;

b += 3;  // Same as: b = b + 3

console.log(b); // 8

✅ 3. Subtraction Assignment (-=)
Subtracts a value from the variable and assigns the result.

let c = 10;

c -= 4;  // Same as: c = c - 4

console.log(c); // 6

✅ 4. Multiplication Assignment (*=)
Multiplies the variable by a value and assigns the result.

let d = 7;

d *= 2;  // Same as: d = d * 2

console.log(d); // 14

✅ 5. Division Assignment (/=)
Divides the variable by a value and assigns the result.

let e = 20;

e /= 5;  // Same as: e = e / 5

console.log(e); // 4

✅ 6. Modulus Assignment (%=)
Divides the variable by a value, assigns the remainder.

let f = 11;

f %= 4;  // Same as: f = f % 4

console.log(f); // 3

✅ 7. Exponentiation Assignment (**=)
Raises the variable to a power and assigns the result.

let g = 3;

g **= 3;  // Same as: g = g ** 3

console.log(g); // 27

3️⃣ Best Practices
✅ Use +=, -=, *=, etc., for concise code.
✅ Use **= for exponentiation instead of Math.pow().
✅ Use %= to check even/odd numbers or find remainders.
