Utilità

Utilities for JavaScript

No genius here - that's just the stuff you toss in your project's utilities file.

Installation

$ npm i utilita

Usage

attempt

Attempts to invoke function, and returns either the result or the default value.

import { attempt } from 'utilita';

attempt(() => JSON.parse('[1, 2, 3]'), []); // [ 1, 2, 3 ]
attempt(() => JSON.parse('[1, 2, ]'), []); // []

set

Assigns a property in a deep clone of the source object.

import { set } from 'utilita';

set({ name: 'Joe' }, 'age', 22); // { name: 'Joe', age: 22 }

replaceAt

Replaces an element at a specified index in a copy of the source array.

import { replaceAt } from 'utilita';

replaceAt([1, 2, 3], 1, 111); // [ 1, 111, 3 ]

removeAt

Removes an element at a specified index in a copy of the source array, and returns both the modified array & the removed element.

import { removeAt } from 'utilita';

removeAt([1, 2, 3, 4, 5], 2).array; // [ 1, 2, 4, 5 ]
removeAt([1, 2, 3, 4, 5], 2).element; // 3
