Assigning a Variable

Saying what the variable name stands for is called assigning the variable. When you update the value, you are assigning it a new value.

It's best to give a variable an initial or starting value when you create it. Not all languages have a default value and some variables default to a null value which could create errors.

How to Assign a Value to a Variable

• Text-based code generally uses a single equal sign (=)

• What follows the = is what is put in the variable

Examples:

Processing and Java-based example:

String name = “Hope”;

float opacity = 0.5;              // Equal to 50%

JavaScript example:

var count = 0;

Python example:

count = 0
