@lvchengbin/is

Is

A JavaScript library for checking the type of a value for browsers.

Installing

npm i @lvchengbin/is --save

Usage

Generally, when we are using some toolkit such as rollup, we don't want to compile a huge library into our project, therefore, to import the files you really need.

import isFunction from '@lvchengbin/is/src/function';
import array from '@lvchengbin/is/src/array';

isFunction( async () => {} );
isArray( [] );

If you want to invoke the whole package:

import is from '@lvchengbin/is';

is.function( () => {} );
is.array( [] );
