@zeinabmahdi/lotide v1.0.0

Lotide

A mini clone of the Lodash library.

Purpose

BEWARE: This library was published for learning purposes. It is not intended for use in production-grade software.

This project was created and published by me as part of my learnings at Lighthouse Labs.

Usage

Install it:

npm install @ZeinabMahdi/lotide

Require it:

const _ = require('@ZeinabMahdi/lotide');

Call it:

const results = _.tail([1, 2, 3]) // => [2, 3]

Documentation

The following functions are currently implemented:

• head([array]): returns the first element in an array.
• tail([array]): returns every element except the head (first element) of the array.
• without([array]): returns a subset of a given array, removing unwanted elements.
• assertEqual(num/str, num/str): compares primitive types (like numbers and strings).
• assertArraysEqual([array],[array]): compares two arrays to ensure the values within them are equal.
• eqArrays([array],[array]): returns true if two arrays are equal.
• middle([array]): takes in an array and return the middle-most element(s) of the given array.
• countLetters('string'): takes in a sentence (in string form) and returns a tally of each of the letters in that sentence.
• letterPositions('string'): returns all the indices (zero-based positions) in the string where each character is found.
• findKeyByValue({object}, value): searches for a key on an object where its value matches a given value.
• eqObjects({object}, {object}): returns true if two objects are equal.
• takeUntil(array, callback): returns a slice of a given array with elements from the beginning until the callback provided returns a truthy value.
• findKey({object}, value): scans the object and return the first key for which the callback returns a truthy value.
• assertObjectsEqual({object}, {object}): compares two objects to ensure the values within them are equal.
• countOnly([array], num): recieves an array of items and return counts for a specific subset of them.
• map([array], callback): produces a new array containing elements of the original array that met the callback function criteria.
