Array Like

Array-like value (any value with length property)

<tt>array-like/is</tt>

Restricted array-like confirmation. Returns true for every value that meets following contraints

• is an object (or with allowString option, a string)
• is not a function
• Exposes length that meets array-length constraints

const isArrayLike = require("type/array-like/is");
 
isArrayLike([]); // true
isArrayLike({}); // false
isArrayLike({ length: 0 }); // true
isArrayLike("foo"); // false
isArrayLike("foo", { allowString: true }); // true 

<tt>array-like/ensure</tt>

If given argument is an array-like, it is returned back. Otherwise TypeError is thrown.

const ensureArrayLike = require("type/array-like/ensure");
 
ensureArrayLike({ length: 0 }); // { length: 0 }
ensureArrayLike("foo", { allowString: true }); // "foo"
ensureArrayLike({}); // Thrown TypeError: null is not an iterable
