Package Exports

has-value

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (has-value) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

has-value

Returns true if a value exists, false if empty. Works for booleans, functions, numbers, strings, nulls, objects and arrays. Other libs do this, but I needed one that would optionally not treat zero as empty.

Install

Install with npm:

npm i has-value --save-dev

Run tests

npm test

Usage

var hasValue = require('has-value');

hasValue('a');
//=> true

hasValue('');
//=> false

hasValue(1);
//=> true

hasValue(0);
//=> false

hasValue(0, true); // treat zero as a value
//=> true

hasValue({a: 'a'}});
//=> true

hasValue({}});
//=> false

hasValue(['a']);
//=> true

hasValue([]);
//=> false

hasValue(function(foo) {}); // function length/arity
//=> true

hasValue(function() {});
//=> false

hasValue(true);
hasValue(false);
//=> true
