Lotide
A mini clone of the Lodash library.
Purpose
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.
Usage
Install it:
npm install @ehabahmed23/lotide
Require it:
const _ = require('@ehabahmed23/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
-
_.head(array)
: Takes an array and returns the first element. -
_.tail(array)
: Takes an array and returns all elements except the first. -
_.middle(array)
: Takes an array and returns the 2 middle element if even and 1 if odd. -
_.eqArrays(arr1, arr2)
: Takes 2 arrays and return true if they are the same and false if they are not. -
_.assertArraysEqual(arr1,arr2)
: Used for testing and needs _.eqArrays to print a message if the 2 arrays are equal. -
_.assertEqual(actual, excpected)
: takes in 2 variables to see if they are strictly equal(used for testing) and prints a message. -
_.eqObjects(obj1, obj2)
: Takes in 2 objects and retuns true if they are strictly equal and false if not. -
_.assertObjectsEqual(array)
: Used for testing and needs _.eqObjects to print a message if the 2 objects are equal. -
_.countletters(array)
: takes in a string and counts how many of each letter was used and returns it in an object -
_.countOnly(array, object)
: takes an array and an object. It will return an object containing counts of everything that the input object listed. -
_.findKey(array)
: Which takes in an object and a callback. It should scan the object and return the first key for which the callback returns a truthy value. If no key is found, then it should return undefined. -
_.findKeyByValue(object, value)
: takes in an object and a value. It should scan the object and return the first key which contains the given value. If no key with that given value is found, then it should return undefined. -
_.letterPositions(string)
: Will return all the indices (zero-based positions) in the string where each character is found. -
_.takeUntil(array, callback)
: Which will keep collecting items from a provided array until the callback provided returns a truthy value. -
_.without(array, itemsToRemove)
: This function should take in a source array and a itemsToRemove array. It should return a new array with only those elements from source that are not present in the itemsToRemove array.
