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 @brianguyen97/lotide
Require it:
const _ = require('@brianguyen97/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
The following functions are currently implemented:
-
function1(countLetters)
: Pass in a string, returns an object showing how many times each letter appears in the string -
function2(countOnly)
: countOnly will be given an array and an object. It will return an object containing counts of everything that the input object listed. -
function3(findKey)
: Takes in an object and a callback. It scans the object and returns the first key for which the callback returns a truthy value. If no key is found, undefined is returned -
function4(findKeyByValue)
: Takes in an object and a value. It scans the object and returns the first key which contains the given value. If no key with that given value is found, then it should return undefined. -
function5(flatten)
: Flatten takes in an array containing elements including nested arrays of elements, and returns a "flattened" version, removed the nested arrays. -
function6(head)
: Takes in an array and returns the first element -
function7(letterPositions)
: Returns all the indicies in the string where each character is found as an object -
function8(map)
: Own version of map, iterates over an array, do something to it, and return a new array. -
function9(middle)
: Returns the most middle element of an array, one element if there is an odd amount, two if it's even. Minimum of 3 elements -
function10(tail)
: Takes in an array, returns a new array with everything besides the first element, the "tail". -
function11(takeUntil)
: Takes in an array and a callback, the function will return a slice of the array, starting from element 0, and it'll keep going until the callback returns a truthy value. -
function12(without)
: Takes in 2 arrays, and return everything from the first array, excluding the elements in the second array. -
function13(assertArraysEqual)
: Takes in 2 arrays, compare them to see if they're equal. -
function14(assertEqual)
: Compares 2 values to see if they're equal -
function15(assertObjectsEqual)
: Compares 2 objects to see if they're equal. -
function16(eqArrays)
: Compares 2 arrays to see if they're equal. -
function17(eqObjects)
: Compares 2 objects to see if they're equal. Returns true or false.
