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 @michaelak/lotide

Require it:

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

Call it:

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

The following functions are currently implemented:

head(): retrieve the first element from the array, the array is not changed
tail(): returns everything except for the first item of the array
middle(): returns the middle items of an array
countLetters(): take in a collection of items and return counts for a specific subset of those items
countOnly(): take in a sentence (as a string) and then return a count of each of the letters in that sentence.
findKey(): takes in an object and a callback, scans the object and return the first key for which the callback returns a truthy value
findKeyByValue(): takes in an object and a value, scans the object and return the first key which contains the given value
letterPositions(): return all the indices (zero-based positions) in the string where each character is found
map(): description
takeUntil(): remove items from the array until a condition is satisfied
without(): return new array, removing unwanted elements from original.
eqArrays(): check if two arrays are the same
eqObjects(): check if two objects are the same
eqObjects():check to see if actual output equals expected
assertEqual():compare two values and check if actual output equals expected
assertArraysEqual(): compare actual array against expected outcome
assertObjectsEqual(): compare actual object against expected outcome
