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.
