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 @seb-2002/lotide
Require it:
const _ = require('@seb-2002/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
-
countLetters(string): countLetters takes a string and returns an object in which each letter appearing in the string is a key and a count is the value. -
eqArrays(arr1, arr2): This function compares arrays and returns a boolean value if they are equivalent. -
countOnly(arr, object): countOnly js take an array and an object. It searches for each instance of a key with a truthy value in the object which appears in the array and outputs a new object with the count of each key. -
eqObjects (obj1, obj2): Compares two objects and returns a boolean (not good for nested objects). -
findKey (obj, callback): Returns the first key in the object for which the value comes back true. -
findKeyByValue(obj, searchItem): If there are keys which correspond to the value of searchItem, it returns an a array of keys. If there is only one key in the array, it returns the value of array[0]. If there are no matching keys, it returns "No keys for that value". -
flatten(array): Flattens a nested array (only good for one layer of nesting). -
head(array): Returns the first element of an array. -
letterPositions(string): Takes a string and returns an object where each letter in the string is a key and an array of its indices is the value. -
map (array, callback): Transforms each element of the array according to the callback. -
middle(array): Returns an array of the middle element(s) of an array. -
tail(array): Returns the array without the first element. -
takeUntil(array, callback): Pushes the array elements to a new array until the callback returns true. -
without(array, removalArray): Outputs a new array with only those items in source which were not in itemsToRemove (source WITHOUT itemsToRemove).
