return the first argument that is !== undefined
Most of the time when I chain together ||
s, I actually just want the first
item that is not undefined
, not the first non-falsy item.
This module is like the defined-or (//
) operator in perl 5.10+.
var defined = require('defined');
var opts = { y : false, w : 4 };
var x = defined(opts.x, opts.y, opts.w, 100);
console.log(x);
$ node example/defined.js
false
The return value is false
because false
is the first item that is
!== undefined
.
var defined = require('defined')
Return the first item in the argument list a, b, c...
that is !== undefined
.
If all the items are === undefined
, return undefined.
With npm do:
npm install defined
MIT
