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 @ife2020/lotide
Require it:
const _ = require('@ife2020/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
head(arr): description - retrieves the first element from an array.tail(arr): description - retrieves the entire array except for the first item/element.middle(arr): description - retrieves the middle elements within the array to return them in array.without(source, itemToRemove): description - removes items from the source array provided an array of items to remove.takeUntil(arr, callback): description - returns a slice of the array with elements taken from the beginning up until the results of the callback function.map(array, callback): description - returns a new array based on teh results of the callback function.letterPositions(string): description - takes in sentence (as a string) and returns all the indices (zero-based positions) in the string where each character is found.findKeyByValue(obj, value): description - 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.findKey(obj): description - scans the object and returns the first key for which the callback returns a truthy value. If no key is found, then it should return undefined.countLetters(string): description - takes in sentence (as a string) and returns a count of each of the letters in that sentence.countOnly(arr, obj): description - takes in a collection of items (array) and returns counts for a specific subset of those items based on the object.eqObjects(obj1, obj2): description - compares to objects for a perfect match.assertEqual(actual, expected): description - compares identical and non-identical strings or numbers (primitive data only).eqArrays(arr1, arr2): description - compares two arrays for a perfect match.assertArraysEqual(actual, expected): description - provides a console log message of whether or not both arrays match the expected output.assertObjectsEqual(actual, expected): description - provides a console log message of whether or not both objects match the expected output.
