6. JavaScript type Operator
1. Arithmetic Operators
Arithmetic operators are used to perform arithmetic on numbers:| Operator | Description |
|---|---|
| + | Addition |
| - | Subtraction |
| * | Multiplication |
| ** | Exponentiation |
| / | Division |
| % | Modulus (Division Remainder) |

| -- | Decrement |
2. Assignment Operators
Assignment operators assign values to JavaScript variables.
| Operator | Example | Same As |
|---|---|---|
| = | x = y | x = y |
| += | x += y | x = x + y |
| -= | x -= y | x = x - y |
| *= | x *= y | x = x * y |
| /= | x /= y | x = x / y |
| %= | x %= y | x = x % y |
3. Comparison Operators
| Operator | Description |
|---|---|
| == | equal to |
| === | equal value and equal type |
| != | not equal |
| !== | not equal value or not equal type |
| > | greater than |
| < | less than |
| >= | greater than or equal to |
| <= | less than or equal to |
| ? | ternary operator |
4. Logical Operators
| Operator | Description |
|---|---|
| && | logical and |
| || | logical or |
| ! | logical not |
5. Bitwise Operators
| Operator | Description | Example | Same as | Result | Decimal |
|---|---|---|---|---|---|
| & | AND | 5 & 1 | 0101 & 0001 | 0001 | 1 |
| | | OR | 5 | 1 | 0101 | 0001 | 0101 | 5 |
| ~ | NOT | ~ 5 | ~0101 | 1010 | 10 |
| ^ | XOR | 5 ^ 1 | 0101 ^ 0001 | 0100 | 4 |
| << | Zero fill left shift | 5 << 1 | 0101 << 1 | 1010 | 10 |
| >> | Signed right shift | 5 >> 1 | 0101 >> 1 | 0010 | 2 |
| >>> | Zero fill right shift | 5 >>> 1 | 0101 >>> 1 | 0010 | 2 |
