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 @patrick-tumu/lotide

Require it:

const _ = require('@patrick-tumu/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• head(array): return the first element of a non empty array if input array is empty return undefined
• tail(array): return the elements of an array - the first element of an array with length greater than 1 otherwise return empty array
• middle(array): if an array is odd return the middle value, if an array if even in length return the average of the middle two values, if the array has a length <= 2 return an empty array
• countLetters(string): takes in a string and returns an object where the letters of the input string become keys and the values are the number of times they occur in the string
• countOnly(array): takes in an array and a value. Returns an object where the value is a key and the paired value of that key is the number of times the input value occurs in the input array
• eqArrays(array1, array2): takes in two arrays returns true if equal and false otherwise
• eqObjects(obj1, obj2): takes in two objects returns true if equal and false otherwise
• findKey(obj1, callback): takes in an object and iterates through the object passing each value into the callback function. Can be used to find key depending on the callback used
• findKeyByValue(obj1, value):takes in an object and a value returns the key of the object associated with input value or undefined
• map(array, callback):takes in an array and a callback function. iterates through the array and returns a new array where every value of input array has been passed into the callback function and pushed in to the result array
• letterPostions(string):takes in a string and returns an object where the letters of the string are the keys and the posistions in which they appear in the original string are the values associated (array).
• takeUntil(array, callback): takes in an array and a callback function returns an array of the original values until one of the original values when passed to the callback returns false
• min(array):takes in an array of numbers and returns a number representing the index where the smallest number is
