TildeJS

NOTE: This library is still at alpha stage, with few functions to offer, few documentations, and no test units yet. Use at your own risk when you intend to use this in your production app. Now this library is functional but not production-ready yet.

The aim of this library is to provide you with a bunch of JS helper functions, including some you might think is hilarious!

How to Use?

import tilde from 'tildejs';

let number = 10;
let falsyValue = undefined;
let emptyStr = ""; //Or any operations that might returns empty string.

console.log(tilde.truthy(falsyValue)) //false
console.log(tilde.falsy(falsyValue)); //true

/**
* Check whether emptyStr is falsy or not.
* But when--for example--you've got any HTML Response
* that is identical to an empty string, you might don't want
* to pass that as an error. Below is how we evaluate the variable
* while pretending the empty string is 'truthy' value.
*/
console.log(tilde.falsyExceptEmptyStr(emptyStr)); //false

//Check whether the number is even
let isEven = tilde.when(number % 2 === 0, () => "even", () => "odd"); //even

What's Inside?

NOTE: The list is still under construction.

Truthy-or-Falsy (TOF)

truthy: Checks whether the value is truthy.
falsy: Checks whether the value is falsy.
truthyExcept: Checks whether the value is truthy except if passed the evaluation callback.
falsyExcept: Checks whether the value is falsy except if passed the evaluation callback.
falsyExceptEmptyStr: Checks whether the value is falsy except if the value is an empty string.
falsyExceptZero: Checks whether the value is falsy except if the value is a number zero.

Conditionable

Inspired by Laravel, this helps you when e.g. you need one-liner but don't want to use ternary operator.

when: Call a callback function (and return something if needed) when the condition is truthy, otherwise call a fallback function.
unless: Call a callback function (and return something if needed) when the condition is falsy, otherwise call a fallback function.
