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 @raficelkouche/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertEqual(actual, expected): checks whether 2 variables of a primitive data type are equal or not, returns a boolean
• assertArraysEqual(actual,expected): checks whether 2 arrays are equal, returns a boolean
• assertObjectEqual(actual,expected): checks whether 2 objects are equal, returns a boolean
• countLetters(string): counts the number of letters in a string (excluding white space)
• countOnly(allItems, itemsToCount): takes in a collection of items and returns a count for a specific subset
• eqArrays(arrayA, arrayB): compares two arrays and returns true if they are equal, otherwise false
• eqObjects(objA, objB): compares two objects and returns true if they are equal, otherwise false
• findKey(object,callback): returns the first key in which the callback function returns a truthy value
• findKeyByValue(object, value): looks for a value in a given object, returns the key where that property exists otherwise returns undefined
• flatten(array): takens in an array of elements (maximum 1 level nesting) and spreads out all the elements
• head(array): returns the first element of an array
• letterPositions(sentence): given a sentence, returns an object with the locations of all the occurrences of all the letters
• map(array,callback): calls the callback function on every element in an array and returns a new array
• middle(array): given an array, returns the middle element. If the array length is odd, returns a single element, otherwise returns an array with 2 elements
• tail(array): returns an array with all the elements of an input except for the first element.
• takeUntil(array, callback): keeps collecting items from a provided array until the callback provided returns a truthy value.
• without(array,arrayOfItemsToRemove): returns an array that contains all the elements that are not part of the arrayOfItemsToRemove array
