typeof-article
Get the native JavaScript type of a value, preceded by the appropriate indefinite article (either a
or an
), for use in error messages.
Install
Install with npm:
$ npm install --save typeof-article
Usage
(A few of the types have some extra formatting where it makes sense. For example, instead of a regexp
, it returns a regular expression
, which IMHO is more readable to users. You can customize mappings if you want)
var type = require('typeof-article');
console.log(type({}));
//=> 'an object'
console.log(type([]));
//=> 'an array'
console.log(type(9));
//=> 'a number'
console.log(type(/abc/));
//=> 'a regular expression'
console.log(type(new WeakMap()));
//=> 'a WeakMap'
Get the object of types-to-articles mappings:
var types = require('typeof-article').types;
Also exposes a typeOf
property, for getting the native type only:
var type = require('typeof-article');
type.types.weapmap = 'a WeakMap()';
console.log(type.typeOf(new WeakMap()));
//=> 'weakmap'
Customize
Customize any of the mappings:
var type = require('typeof-article');
type.types.weapmap = 'a WeakMap()';
console.log(type(new WeakMap()));
//=> 'a WeakMap()'
