ens

Easily ensure data types.


---

Why

``js
// Ensure variable obj is an object, the traditional way
obj = (typeof obj === 'object' && !(obj instanceof Array)) ? obj : {};
`

`js
// Ensure variable obj is an object, using ens.obj
obj = ens.obj(obj);
`

ens makes it easy to ensure JS data types. With JS, ensuring data types requires a lot of ugly code. It's easy to specify variable defaults though: obj = obj || {}. The problem with this pattern is, when obj is set to a value which evaluates to true, the default value {} won't be bound to obj. This is where ens comes in: obj = ens.obj(obj). Which results in the binding of an object to obj no mather what type of data obj is.

Install

npm install ens

Use

`js
var ens = require('ens');

ens.arr(); // []
ens.arr({}); // []
ens.arr([1, 2]); // [1, 2]

ens.boo(); // true
ens.boo({}); // true
ens.boo(false); // false

ens.fun(); // function () {}
ens.fun({}); // function () {}
ens.fun(function test() {}); // function test () {}

ens.num(); // 1
ens.num({}); // 1
ens.num(5); // 5

ens.obj(); // {}
ens.obj([]); // {}
ens.obj({a: 'b'}); // {a: 'b'}

ens.str(); // ''
ens.str({}); // ''
ens.str('test'); // 'test'
``
