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.
npm install @seb-2002/lotide
const _ = require('@seb-2002/lotide');
const results = _.tail([1, 2, 3]) // => [2, 3]
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. 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).
