@lucyshen/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 @lucyshen/lotide

Require it:

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

Call it:

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

The following functions are currently implemented:

head: Returns the first element of an array
tail: Returns the tail end of an array after the first element
middle: Returns the middle element of an array (single element for odd number of elements, two elements for even number of elements)
countLetters: Returns an object counting the number of times a letter appears in a string
countOnly: Given an array of strings and an object specifying what to count, returns a count of how many instances of each string were found in the array
findKey: Given an object and a callback, scan the object and returns the first key for which the callback returns a truthy value
findKeyByValue: Given an object and a value, scan the object and return first key with the given value
flatten: Given an array with other arrays inside, it can flatten it into a single-level array
letterPositions: Returns an object with all the letters that appear in a string, and
map: Given an array and a callback function, performs the function on all elements in the array and returns a new array
takeUntil: Given an array and a callback function, return a new array until the callback condition is met
without: Given a source array and an items to remove array, returns a new array without the specific items
eqArrays: Returns true if each element in two arrays have a perfect match
eqObjects: Returns true if both objects have identical keys with identical values
