# typecheck-string - use `angular.isString` instead of `typeof` comparisons

You should use the angular.isString method instead of the default JavaScript implementation (typeof "" === "[object String]").

**Rule based on Angular 1.x**

## Examples

The following patterns are considered problems;

    /*eslint angular/typecheck-string: 2*/

    // invalid
    typeof someString === 'string' // error: You should use the angular.isString method

The following patterns are **not** considered problems;

    /*eslint angular/typecheck-string: 2*/

    // valid
    angular.isString(someString);

## Version

This rule was introduced in eslint-plugin-angular 0.1.0
