Convert an argument into a valid iterator. Based on the .makeIterator() implementation in mout

Please consider following this project's author, Jon Schlinkert, and consider starring the project to show your :heart: and support.


Install with npm:

$ npm install --save make-iterator

Although the code has materially changed, this was originally based on the make iterator function in moutjs, and externalized to a module. Thanks to the moutjs team for the inspiration.

var iterator = require('make-iterator');


var arr = ['a', 'b', 'c', 'd', 'e', 'f'];
var fn = iterator(/[a-c]/);
//=> ['a', 'b', 'c'];


var fn =  iterator({ a: 1, b: { c: 2 } });

console.log(fn({ a: 1, b: { c: 2, d: 3 } }));
//=> true
console.log(fn({ a: 1, b: { c: 3 } }));
//=> false
