Operators in JavaScript

The JavaScript language provides a wealth of operators for performing various operate. These operators can be divided into the following categories:

1. Arithmetic operators

  • Addition ( ): Add two or more numbers.
  • Subtraction (-): Subtract one number from another number.
  • Multiplication (*): Multiply two numbers.
  • Division (/): Divide one number by another number.
  • Modulo (%): Take the remainder of the division of two numbers.
  • Increment ( ): Add 1 to a number.
  • Decrease (--): Decrease a number by 1.

2. Assignment operator

  • Single equal sign (=): Assign a value to a variable.
  • Add equals (=): Add a value to a variable.
  • Minus equals (-=): Subtract a value from a variable.
  • Multiply equals (*=): Multiply a variable by a value.
  • Division equals (/=): Divide a variable by a value.

3. Comparison operator

  • Equal (==): Compares whether two values ​​are equal.
  • Strict equals (===): Compares whether two values ​​are equal and of the same type.
  • Not equal to (!=): Compares whether two values ​​are not equal.
  • Not strictly equal (!==): Compares whether two values ​​are not equal or have different types.
  • Greater than (>): Compares whether one value is greater than another value.
  • Greater than or equal to (>=): Compares whether a value is greater than or equal to another value.
  • Less than (<): Compares whether one value is less than another value.
  • Less than or equal to (<=): Compares whether one value is less than or equal to another value.

4. Logical operators

  • And (&&): Returns true only if both operands are true.
  • Or (||): Return true as long as one operand is true.
  • Not (!): Negate a value.

5. Bitwise operators

  • Bitwise AND (&): performs an AND operation on each bit of two numbers.
  • Bitwise OR (|): OR operation on each bit of two numbers.
  • Bitwise XOR (^): Performs XOR operation on each bit of two numbers.
  • Bitwise left shift (<<): Shift the bits of a number to the left by the specified amount.
  • Bitwise right shift (>>): Move the bits of a number to the right by the specified amount.

6. Other operators

  • Comma (,): used to separate two or more expressions.
  • Question mark (?): used for ternary conditional operations.
  • Colon (:): used for ternary conditional operations.
