arrayiffy-if-string3.12.0
Put non-empty strings into arrays, turn empty-ones into empty arrays. Bypass everything else.
§ Quick Take
import { strict as assert } from "assert";
import arrayiffy from "arrayiffy-if-string";
assert.deepEqual(arrayiffy("aaa"), ["aaa"]);
assert.deepEqual(arrayiffy(""), []);
assert.equal(arrayiffy(true), true);
assert.equal(arrayiffy(), undefined);
§ Purpose
- If it's a non-empty string, put it into an array and return it.
- If it's empty string, return an empty array.
- If it's anything else, just return it.
It's main purpose is to prepare the input argument options' objects.

.
§ API
arrayiffy(something)
In other words, it's a function which takes one input argument.
§ Competition
Mr. Sorhus' arrify
API is slightly different, it casts everything to array (null
into empty array, for example). arrayiffy-if-string
on other hand, wraps only strings into arrays, bypassing the rest (null
into null
, for example).
It depends what you need.
