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 @thilakshan.arulnesan/lotide

const _ = require('@thilakshan.arulnesan/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
head(array)
: Given an array, will return the first element.tail(...)
: Given an array, will return an array containing everything except the first element.eqArrays(...)
: Checks if two arrays are equal and returns a boolean.assertArraysEqual(...)
: Checks if two arrays are equivalent and prints out to a log of the test.middle(...)
: Returns the middle element (if there are an even number of elements, the middle two elements are returned instead).assertEqual(...)
: Checks if two elements are equalcountLetters(...)
: Given a string, returns an object with every letter in the string as a key and the values as the number of time that letter occurs.countOnly(...)
: Given an array and an object indicating which strings to look for (keys = string, values = true/false), this function will return an object containing indicating how many times the string appears in the array.eqObjects(...)
: Checks if two objects are equivalent (same keys and values) and returns a boolean.assertObjectsEqual(...)
: Prints out whether two arrays are equal or notfindKey(...)
: Given an object and a function will return all the keys that satisfy the function.findKeyByValue(...)
: Given an object and a value, returns the first key in the object that has the given value.flatten(...)
: Given an array that contains sub-arrays, returns an array containing a single array containing no subarrays but contains all the original elements.letterPositions(...)
: Given as string, returns an object which has all the letters as keys and the value is an array of all the indexes where the letter appears.map(...)
: Given an array and a function, map will return an array where the callback is applied to each element.takeUntil(...)
: Given an array and a function, returns all elements from index 0 until the first element which causes the function to return false.without(...)
: Given two arrays, array1 and array2, will return the subset of elements in array1 that are NOT in array2 (this is returned as an array).
