@teddyleung/lotide NPM

Lotide

A mini clone of the Lodash library.

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.

Install it:

npm install @teddyleung/lotide

Require it:

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

Call it:

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

The following functions are currently implemented:

countLetters: Takes a string and returns an object with the count of each letter
countOnly: Takes one array of elements and a second array of items to search and returns an object with the count of each item searched
eqArrays: Takes two arrays and checks for equality
eqObjects: Takes two objects and checks for equality
findKey: Takes an object and a callback function and returns the key of the object where the callback evaluates to true
findKeyByValue: Takes an object and a value and finds the key that corresponds to the value
flatten: Flattens multi-layer arrays
head: Takes an array and returns the first element
letterPositions: Takes a string and returns an object with keys of each letter and values which are arrays of the letter positions
map: Takes an array and a callback, applies the callback to each element in the array, and returns the new array
middle: Takes an array and returns an array of the middle element if length is odd or the middle two elements if length is even
tail: Takes an array and returns all elements other than the first
takeUntil: Takes an array and a callback and returns an array of elements up to the element where the callback returns true
without: Takes two arrays and returns the first array without items that exist in the second array
