@firebfm/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 @firebfm/lotide

Require it:

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

Call it:

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

The following functions are currently implemented:

head(arr): return first item
countLetters(str): return a count of each letter
countOnly(allItems, itemsToCount): allItems: an array of strings that we need to look through, itemsToCount: an object specifying what to count
assertArraysEqual(arr1, arr2): assert if two arrs are equal
assertEqual(value1, value2): assert if 2 values are equal
assertObjectsEqual(obj1, obj2): assert if 2 objs are equal
eqArrays(arr1, arr2): check for equality between 2 arrays.
eqObjects(obj1, obj2): check that 2 objects are equal.
findKey(obj, callback): callback returns a truthy value, scan the object for the first key that matches
findKeyByValue(obj, value): returns the key of the value.
letterPositions(str): returns all the indices/position of each character in the string
map(arr, callback): apply the callback on the arr
middle(arr): returns the middle element of an array
tail(arr): returns the array except for the first element
takeUntil(arr, callback): returns an array until the callback stop condition
without(source, itemsToRemove): returns a new array based on filter
