Utils

Sets of utils for JS.

How to install

npm install -D @dbetka/utils

Base usage

You can import below sets of utils:

• check,
• object,
• array,
• promise,
• request,
• validate

in two different ways:

import u from '@dbetka/utils';

u.check.isUndefined(someValue);

import { uCheck } from '@dbetka/utils';

uCheck.isUndefined(someValue);

I will show you examples only in first way.
