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 @aiman03at/lotide

Require it:

const _ = require('@aiman03at/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 an array containing all the elements from main array except the first element.

  middle(arr): Returns 1 middle element from array arr if length of array is negative else 2 middle elements if the length is positive.

  assertAraysEqual(array1,array2) : Checking two arrays are equal and consoles if assertion is passed or failed.

  assertEqual(actual,expected) : Console logs passed if two values are same else Failed if actual is not equal to expected.

  assertObjectsEqual(object1, object2) :Assertion message-Assertion passed if both objects are equal else Assertion fail.

  countLetters(sentence) : Take in a sentence (as a string) and then returns the count of each of the letters in that sentence.

  countOnly(array, object) : Take in an array of strings that we need to look through and an object specifying what to count and returns counts for a specific subset of those items.

  eqArrays(array1, array2) : Evaluates if the two arrays are a perfect match. Returns true for matching arrays and false for unmatched arrays.

  eqObjects(object1, object2) : Evaluates if the two objects are a perfect match. Returns true for matching objects and false for unmatched objects.

  findKey(object, callback) : Return the first key for which the callback returns a truthy value.

  findKeyByValue(object, value) : Search through the Object to check the corresponding key for the given val and returns the key.

  flatten(array) : Flatten a multidimensional array into one -dimensional array and returns it.

  letterPositions(sentence) : Takes in an sentence as input and returns all the indices (zero-based positions) in the string where each character is found.

  map(array,callback) : Evaluates the input array for the callback and returns a new array based on the results of the callback function.

  takeUntil(array, callback) : Return a new array based on the results of the callback function.

  without(array1, array2) : Array with all the elements from array1 arr without the elements in subarray array2.
