JSLint says new keyword is missing [duplicate]

• How to fix JSLint “missing new” error 2 answers

Let's say I have some JavaScript that looks like this:

function A() {

  var MyVar, SomeParameter;

  // do work

  MyVar = FunctionB(SomeParameter);

}

JsLint says I'm Missing 'new'. at the line MyVar = FunctionB(SomeParameter);

Why should I rewrite as MyVar = new FunctionB(SomeParameter); Is there going to be any benefit?

Answer 1

It is the convention that constructors (eg: Array, Object) are starting with a capital.

JSLint complains, because it thinks that you're trying to use a constructor, without new keyword. To fix the problem, start your function with a non-uppercase character.

Answer 2

JSLint thinks the function is a constructor since it's uppercase. Name your non-constructor functions with an initial lowercase letter and JSLint will stop complaining.
