An operator provides a result by performing an action on a single or more operands .
Arithmetic Operators
| Operator | Description | Example |
|---|
| + | Addition | 100 + 50 = 150 |
| - | Subtraction | 100 - 50 = 50 |
| * | Multiplication | 100 * 50 = 5000 |
| / | Division | 100 / 50 = 2 |
| % | Modulus (Remainder) | 100 % 50 = 0 |
| ++ | Increment | var val=2; val++; Now val = 3 |
| -- | Decrement | var val=2; val--; Now val = 1 |
Assignment Operators
| Operator | Description | Example | |
|---|
| = | Assign | x = y | x = y |
| += | Add and assign | x += y | x = x + y |
| -= | Subtract and assign | x -= y | x = x - y |
| *= | Multiply and assign | x *= y | x = x * y |
| /= | Divide and assign | x /= y | x = x / y |
| %= | Modulus and assign | x %= y | x = x % y |
Comparison Operators
| Operator | Description |
|---|
| == | Is equal to |
| === | Is equal value and equal type |
| != | Is not equal |
| !== | Is not equal value or not equal type |
| > | Is greater than |
| < | Is less than |
| >= | Is greater than or equal to |
| <= | Is less than or equal to |
| ? | ternary operator |
