JavaScript has numerous operators that can be used, in part, to do mathematical calculations, assign values to variables, and compare values.

Below are just a few examples of these operators. After each section there is a link to a reference page for each, showing the complete list of operators and how they are used.

JavaScript arithmetic operators are used to perform arithmetic between variables and/or values.

let x = 3 + 2; // answer: 5

let x = 3 - 2; // answer: 1

let x = 3 * 2; // answer: 6

let x = 3 / 2; // answer: 1.5

JavaScript assignment operators are used to assign values to variables.

let x = y; // x will equal y

let x += y; // same as x = x + y

JavaScript comparison operators are used in logical statements to determine equality or inequality between variables and/or values.

x == 8 // determines if x is equal to 8

x != 8 // determines if x is NOT equal to 8

x > 8 // determines if x is greater than 8

x <= 8 // determines if x is less than or equal to 8
