Extended typeof

mkd_typeof

Small extended typeof.

Very often we find ourselves adding the same set of checks in addition to typeof so we set them as a module.

usage

Load module

Classical NodeJS way:

const mkd_typeof = require('mkd_typeof');

New EcmasScript syntax available to NodeJS or browsers with, say, Babel:

import mkd_typeof from 'mkd_typeof';

For browsers it will be loaded as with any other module.

Using

console.log(mkd_typeof(null));
console.log(mkd_typeof({}));
console.log(mkd_typeof([]));

Sample:

> mkd_typeof([]);
'array'
> mkd_typeof(null)
'null'
> mkd_typeof({});
'object'
> mkd_typeof(undefined);
'undefined'
> mkd_typeof(-Infinity);
'infinity'
> mkd_typeof(NaN);
'nan'
> mkd_typeof(1);
'number'
> mkd_typeof(1.0);
'number'
> mkd_typeof('1');
'string'

Install

NodeJS:

$ npm install --save mkd_typeof

Browser:

<script src="/path/to/mkd_typeof.js"></script>

Caveats

Numbers created with new Number(...) are detected as numbers but we're not sure it wouldn't be better to let them seen as objects.
