Always choose self-describing function names

Function names should start with a verb

Functions are supposed to do things.

And since verbs describe what is done, start your function name with the exact verb to describe what is going to happen.

• Bad: var priceConvertor = function() {};
• Good: var convertPrice = function() {};
• Better: var convertCanadiantoAmericanDollars = function() {};

Use camelCase for functions

camelCase has all the words grouped together. It has the first word lowercase, and the first letter of all remaining words capitalized.

• Bad: var Get_Location = function() {};
• Good: var getLocation = function() {};
• Good: var extractUserName = function() {};

Use CapsFirst and nouns for object constructors

Object constructors are for creating objects from a general template that have properties and methods attached to them.

By their nature, objects tend to be simple nouns.

• Bad: var kitty = new kindOfAnimal();
• Good: var kitty = new KindOfAnimal();
• Good: var yaris = new Car();
