Readme
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. Also, this works with booleans and other values that other libs fail to test properly.
npm i has-values --save
Install dev dependencies.
npm i -d && npm test
var hasValue = require('has-values');
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
To test for empty values, do:
function isEmpty(o, isZero) {
return !hasValue(o, isZero);
}
