I have this error with JSLint: W040 - Possible strict violation.

But i couldn't find an article about this error on the website.

This error happened when you use the strict mode and you want to call a function (to have a private method for example).

For example:

function Foo() {
  this.toto = 42;
  bar.call(this);
}

function bar() {
  console.log(this.toto);
}
