fast-isnumeric

The fast way to check if a JS object is numeric

Install

npm install fast-isnumeric

API

1var isNumeric = require('fast-isnumeric');
2
3isNumeric(/* any JS object */);

How fast

Run comparison on jsperf: http://jsperf.com/isnumeric-jquery-and-alternate/5

Warning

Please look up the test cases in test.js before using this module.

Most importantly, fast-isnumeric returns false on number and string constructors. That is, isNumeric(new Number(1)) and isNumeric(new String('1')) are false.

Tests

Test locally with karma:

npm test

Why?

In plotly's javascript graphing library plotly.js numerical objects must be accounted for in numerous hot code paths. Inspired by Jon Schlinkert's is-number, fast-isnumeric is significantly simplified and sped up by ignoring number and string constructors.
