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 @username/lotide
Require it:
const _ = require('@username/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
The following functions are currently implemented:
assertArraysEqual
: console logs a message indicating if 2 given arrays are or not equalassertEqual
: console logs a message indicating if 2 given primitive values are or not equalassertObjectsEqual
: console logs a message indicating if 2 given objects have or not the same propertiescountLetters
: receives a string as argument and returns an object with the all the letters from the string as key and the times that letter is repeated as valuecountOnly
: returns how many instances of each string were found in a given string arrayeqArrays
: returns true if 2 given arrays are equal and false if they are noteqObjects
: returns true if 2 given objects have the same properties and false if they don'tfindKey
: takes an object and a callback, scans the object and returns the first key similar to the callback result.findKeyByValue
: takes an object and a property value as arguments and returns the correspondent key or undefined if the key is not in the objectflatten
: transform a 1 level matrix into an array with the values that it contains.head
: console logs a message indicating if 2 given primitive values are or not equalletterPositions
: takes a string and a letter and returns an array with the indexes where that letter was found in the string.middle
: returns an array with the middle value of a given array. If the given array 0, 1 or 2 values it returns an empty array; if it has more than 3 values and its quantity is even it returns 2 middle value and if the quantity is odd it returns the middle valuetail
: takes an array and returns a copy without the first valuetakeUntil
: returns a new array taking the elements from the beginning of given array stoping when the condition in a given callback function is fullfilledwithout
: takes 2 arrays, 1 with a set of values and other with the values to be removed from the first one and returns an array with the remaining values
