JavaScript operators are symbols. They perform actions on values and variables. You use them to build logic.

Use arithmetic operators for math.

• • Addition: 5 + 2 = 7
• • Subtraction: 5 - 2 = 3
• • Multiplication: 5 * 2 = 10
• / Division: 5 / 2 = 2.5
• % Modulus: 5 % 2 = 1
• ** Exponentiation: 5 ** 2 = 25

Use assignment operators to set values.

• = assign
• += add and assign
• -= subtract and assign
• *= multiply and assign
• /= divide and assign
• %= remainder and assign

Use comparison operators to check values.

• == equal to
• === equal value and type
• != not equal
• !== not equal value or type

• greater than

• < less than

• = greater than or equal to

• <= less than or equal to

Use logical operators for conditions.

• && logical AND
• || logical OR
• ! logical NOT
• ?? nullish coalescing

Use bitwise operators for binary bits.

• & bitwise AND
• | bitwise OR
• ^ bitwise XOR
• ~ bitwise NOT
• << left shift

• signed right shift

• unsigned right shift

Use these for text and short logic.

• • joins strings
• ?: ternary operator

Use special operators for specific tasks.

• typeof checks the type
• instanceof checks the class
• delete removes a property
• in checks for a property
• ?. accesses nested values
• ... expands arrays or objects
