This project was created and published by me as part of my learnings at Lighthouse Labs.

Usage

Install it:

npm install @anthonykao10/lotide

Require it:

const _ = require('@anthonykao10/lotide');

Call it:

const results = _.tail([1, 2, 3]) // => [2, 3]

Documentation

The following functions are currently implemented:

• head(array): returns the first item in an array.
• tail(array): returns everything except for the first element in an array.
• middle(array): returns the middle-most element(s) of a given array.
• countLetters(string): returns an object containing the frequency of each letter in input string.
• countOnly(allItems, itemsToCount): given an array of items, returns the counts for a specific subset of those items.
• eqArrays(array1, array2): returns true if two arrays are the same (deep).
• eqObjects(object2, object2): returns true if two objects are the same (deep).
• findKey(object, callback): given an object and a callback, returns the first key for which the callback returns a truthy value. (Returns undefined if no match is found).
• findKeyByValue(object, value): given an object and a value, returns the first key which contains the given value. (Returns undefined if no match is found).
• flatten(array): given an array of arrays, return the array flattened to 1-dimension (only supports a single level of nesting).
• letterPositions(string): returns an object of arrays, which contain all the indices (zero-based positions) in the input string where each character is found. (Array stores each occurrence of a letter).
• map(array, callback): return a new array with each element transformed through the callback.
• takeUntil(array, callback): given an array and callback, passes each element of the array into the callback, returning all elements until the callback returns a 'truthy' value.
• without(source, itemsToRemove): returns a subset of a given array, removing unwanted elements.
