Lesson 3. Variables in javascript

Variables

Variables are memory locations that are given names and can be assigned values. We use variables to store data in memory for later use.

Variable names
Once a value is stored in a variable it can be accessed using the variable name. A variable name can consist of alphanumeric characters and the underscore. It cannot begin with a numeral, though. Note that variable names are case sensitive and first_name is not the same as FIRST_name.

      name2
      _car
