This article will explain in detail how to use arithmetic operators and assignment operators in JavaScript. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

JavaScript operator

The operator = is used for assignment. The operator = is used to assign values to JavaScript variables.

The operator + is used to add value. The arithmetic operator + is used to add up values.

Note: after the above statement is executed, the value of x is 7.

JavaScript arithmetic operator

Arithmetic operators are used to perform arithmetic operations between variables and / or values. Given yard5, there are:

X=y+2 / / + (plus) x=7x=y-2 / /-(minus) x=3x=y*2 / / * (multiply) x=10x=y/2 / (divide) x=2.5x=y%2 / /% (find the remainder) x=1x=++y / / + (accumulate) x=6x=--y /-- (decreasing) xQuest 4

JavaScript assignment operator

The assignment operator is used to assign values to JavaScript variables. Given xflux 10 and ytree 5, there are:

Xchangy / / = (equivalent to x=x+y) x=5x+=y / / + = (equivalent to x=x+y) x=15x-=y / /-= (equivalent to x=x-y) x=5x*=y / / * = (equivalent to x=x*y) x=50x/=y / = (equivalent to x=x/y) x=2x%=y / /% = (equivalent to x=x%y) xroom0

+ operator for strings

The + operator is used to add (concatenate) text values or string variables.

To concatenate two or more string variables, use the + operator.

Txt1= "What a very"; txt2= "nice day"; txt3=txt1+txt2

Note: after the above statement is executed, the variable txt3 contains a value of "What a verynice day".

Tip: to add a space between two strings, you need to insert the space into a string:

Txt1= "What a very"; txt2= "nice day"; txt3=txt1+txt2

Or insert spaces into the expression:

Txt1= "What a very"; txt2= "nice day"; txt3=txt1+ "" + txt2

Note: after the above statement is executed, the variable txt3 contains the value "What a very nice day"

Add strings and numbers

If you add a number to a string, the result becomes a string.

[xss_clean] (x); [xss_clean] (""); x = "5" + "5"; [xss_clean] (x); [xss_clean] ("); x xss_clean +" 5 "; [xss_clean] (x); [xss_clean] ("); x = "5" + 5; [xss_clean] (x); [xss_clean] (") This is the end of the article on "how to use arithmetic operators and assignment operators in JavaScript".
