How to use JavaScript operator, arithmetic operator and assignment operator

This article mainly introduces the relevant knowledge of "how to use JavaScript operator, arithmetic operator and assignment operator". Xiaobian shows you the operation process through actual cases. The operation method is simple and fast and practical. I hope this article "how to use JavaScript operator, arithmetic operator and assignment operator" can help you solve the problem.

JavaScript operator

Assign values to variables and add them:

Var x = 7; / / assign a value of 5 to x

Var y = 8; / / assign a value to y 2

Var z = x + y; / / assign a value to z (x + y) 7

The assignment operator (=) assigns a value to a variable.

Assignment

Var x = 15

The addition operator (+) adds to the number:

Addition

Var x = 7

Var y = 8

Var z = x + y

The multiplication operator (*) multiplies numbers:

Multiplication

Var x = 7

Var y = 8

Var z = x * y

JavaScript arithmetic operator

The arithmetic operator is used to perform arithmetic operations on numbers:

Operator description

+ addition

-subtraction

* multiplication

/ division

% Modulus (remainder)

+ + add

-- decreasing

Note: the chapter on JS arithmetic provides a complete description of the arithmetic operator.

JavaScript assignment operator

The assignment operator assigns values to the JavaScript variable.

The operator example is equivalent to

= 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

The addition assignment operator (+ =) adds a value to the variable.

Assignment

Var x = 7

X + = 8
