Variables

Variables in JavaScript are defined by using the var operator (short for variable), followed by the variable name, such as:



var test = "hi";

In this example, the variable test is declared and given an initialization value of "hi" (a string).

You can also define two or more variables using the same var statement:



var test = "hi", test2 = "hola";

Variables using the same var statement don't have to be of the same type:



var test = "hi", age = 25;

variables in JavaScript do not require initialization:



var test;
