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.
npm install @cjfelice/lotide
const _ = require('@cjfelice/lotide');
const results = _.tail([1, 2, 3]) // => [2, 3]
The following functions are currently implemented:
assertArraysEqual(firstArr, secondArr): confirms if arrays are equal.
assertObjectsEqual(firstObj, secondObj): confirms if objects are equal.
countLetters(string): outputs an object containing letter counts for each letter in a string.
countOnly(array, value): counts how many of a given value exist in an array.
eqArrays(firstArr, secondArr): checks if two arrays are equal.
eqObjects(firstObj, secondObj): checks if two objects are equal.
findKey(object, callback): finds and outputs given key if it exists in given object.
findKeyByValues(object, value): outputs the key of a value if it exists in an object.
flatten(array): un-nests an array and outputs a single basic array of all elements.
head(array): returns the first element in an array.
letterPositions(string): returns an object containing details on each letter in a string and its string locations.
map(array, callback): takes in an array and returns a new array with each element modified by an input callback.
middle(array): returns a new array comprised of the middle one or two elements of input.
tail(array): returns a new array without the first element of the original.
takeUntil(array, callback): returns a new array with the same elements of original up until a chosen callback is true.
without(array, value): returns a new array with all instances of a chosen value removed.
