Explain JavaScript Operators

Sure! JavaScript operators are symbols used to perform operations on operands (values and variables). They can be categorized into several types:

1. Arithmetic Operators

These operators perform basic arithmetic operations.

Addition (+): Adds two numbers.

let a = 5;
let b = 3;
console.log(a + b); // Output: 8

Subtraction (-): Subtracts the second number from the first.
```
console.log(a - b); // Output: 2
```
Multiplication (*): Multiplies two numbers.
```
console.log(a * b); // Output: 15
```
Division (/): Divides the first number by the second.
```
console.log(a / b); // Output: 1.6666666666666667
```
Modulus (%): Returns the remainder of the division.
```
console.log(a % b); // Output: 2
```
Exponentiation ()**: Raises the first number to the power of the second.
```
console.log(a ** b); // Output: 125
```

2. Assignment Operators

These operators assign values to variables.

Assignment (=): Assigns the value on the right to the variable on the left.
```
let c = 10;
```
Addition Assignment (+=): Adds the right operand to the left operand and assigns the result to the left operand.
```
c += 5; // Equivalent to c = c + 5
console.log(c); // Output: 15
```
Subtraction Assignment (-=): Subtracts the right operand from the left operand and assigns the result to the left operand.
```
c -= 3; // Equivalent to c = c - 3
console.log(c); // Output: 12
```
Multiplication Assignment (*=): Multiplies the left operand by the right operand and assigns the result to the left operand.
```
c *= 2; // Equivalent to c = c * 2
console.log(c); // Output: 24
```
Division Assignment (/=): Divides the left operand by the right operand and assigns the result to the left operand.
```
c /= 4; // Equivalent to c = c / 4
console.log(c); // Output: 6
```

3. Comparison Operators

These operators compare two values and return a boolean value.

Equal (==): Checks if two values are equal.
```
console.log(a == 5); // Output: true
```
Not Equal (!=): Checks if two values are not equal.
```
console.log(a != 5); // Output: false
```
Strict Equal (===): Checks if two values are equal and of the same type.
```
console.log(a === 5); // Output: true
```
Strict Not Equal (!==): Checks if two values are not equal or not of the same type.
```
console.log(a !== "5"); // Output: true
```
Greater Than (>): Checks if the left value is greater than the right value.
```
console.log(a > b); // Output: true
```
Less Than (<): Checks if the left value is less than the right value.
```
console.log(a < b); // Output: false
```
Greater Than or Equal (>=): Checks if the left value is greater than or equal to the right value.
```
console.log(a >= b); // Output: true
```
Less Than or Equal (<=): Checks if the left value is less than or equal to the right value.
```
console.log(a <= b); // Output: false
```

4. Logical Operators

These operators perform logical operations.

AND (&&): Returns true if both operands are true.
```
console.log(true && false); // Output: false
```
OR (||): Returns true if at least one of the operands is true.
```
console.log(true || false); // Output: true
```
NOT (!): Inverts the boolean value.
```
console.log(!true); // Output: false
```

5. Bitwise Operators

These operators perform bit-level operations.

AND (&): Performs a bitwise AND.

console.log(a & b); // Output: 1 (binary: 0101 & 0011 = 0001)

OR (|): Performs a bitwise OR.

console.log(a | b); // Output: 7 (binary: 0101 | 0011 = 0111)

XOR (^): Performs a bitwise XOR.

console.log(a ^ b); // Output: 6 (binary: 0101 ^ 0011 = 0110)

NOT (~): Performs a bitwise NOT.

console.log(~a); // Output: -6 (binary: ~0101 = 1010)

Left Shift (<<): Shifts bits to the left.

console.log(a << 1); // Output: 10 (binary: 0101 << 1 = 1010)

Right Shift (>>): Shifts bits to the right.

console.log(a >> 1); // Output: 2 (binary: 0101 >> 1 = 0010)

6. Ternary Operator

The ternary operator is a shorthand for an if-else statement.

Conditional (?:): Returns a value based on a condition.

let isAdult = (a > 18) ? "Yes" : "No";
console.log(isAdult); // Output: No

7. Type Operators

These operators determine the type of a variable.

typeof: Returns the type of a variable.

console.log(typeof a); // Output: number

instanceof: Checks if an object is an instance of a specific class.

let date = new Date();
console.log(date instanceof Date); // Output: true

These are the basic JavaScript operators with examples to illustrate their usage.
