Variables are nothing more than a way to store information in memory. A variable can be a number, a single character, a string of characters making up a work or sentence, or a value indicating whether something is true or false. In JavaScript you declare a variable by giving it a name and assigning a value to it. You can then access this data at any time and, more importantly, change either the content of the variable whenever necessary (hence the name ''variable'').
 
Variables are assigned and manipulated using operators which will be covered in a later chapter. At this stage it is important to understand one operator in particular - the assignment operator.
