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 @vvalentinv/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head(array): returns the first element of the array
• tail(array): returns a copy of the array without the first element
• middle(array): returns the middle value of an array that has at least three elements, if the length is an odd number it will return an array with two elements
• without(array1,array2): returns a copy of the first array without elements in the second array
• takeUntil(array,action): returns an array containing all elements for which the callback returns false.
• map(arr, action): returns an array for which the action transformed each element
• letterPositions(sentence): returns an object with the unique letters and their indices in the sentence.
• findKeyByValue(object, value): returns the first key that matches the value
• findKey(object,action): returns the first key for which the action returns true
• eqObjects(object1,object2): returns true if the objects are equal
• eqArrays(array1,array2): returns true if the arrays are equal
• countOnly(object1,object2): returns an object containg keys from the first object and their number of occurences only if in the second object their value is true
• countLetters(sentence): returns an object listing all unique letters and their number of occurrences
• assertEqual(value1,value2): returns an nice formated message if the values are equal
• assertObjectsEqual(object1,object2): returns an nice formated message if the objects are equal
• assertArraysEqual(array1,array2): returns an nice formated message if the arrays are equal
