angularjs promises use the word finally. grunt jshint complains

Question

AngularJS allows the use of finally after the return of a promise. However, when I have a grunt-jshint running I keep getting

Expected an identifier and instead saw 'finally' (a reserved word).

Does any one know how to turn this off in jshint?

Answer 1

es5 option

This option enables syntax first defined in the ECMAScript 5.1 specification. This includes allowing reserved keywords as object properties.

If you are using a version of jshint prior to 2.0.0, then you have the option of setting an es5 flag. Starting with 2.0.0, es5 is the default. I assume you are using an older version.

Alternatively

You can also say promise['finally'](function(){}); rather than promise.finally(function(){});
