Javascript Guidelines

Javascript ignores whitespace

The two lines below process exactly the same since Javascript ignores whitespace.

var myName="Francis";
var myName = "Francis" ;

Javascript Is Case Sensitive

The two variables below are different due to the variation in uppercase and lowercase letters in the variable naming. They are treated as two separate objects because Javascript is case sensitive.

var myname = "Joe";
var MyName = "Joe";

Naming your variables and functions

When creating variable and function names do not start them with a number. You can use numbers within the name, but just not as the first character. Another good rule of thumb is to use only letters, numbers and underscores when naming things.

var 3rd_name = "Erica"; // will cause script to fail
var name_3 = "Erica"; // will process just fine

Javascript Reserved Words

There are some reserved words that are part of Javascript syntax that we should try not use as variable/function names when we create and use objects while coding Javascript. In some cases using the reserved words can make your script operate unexpectedly.
