@daveclaveau/lotide v1.0.0

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 @daveclaveau/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head(arr): returns the zeroeth indexed value of an array.
• tail(arr): returns the tail of the array, which is everything but the zeroethvalue of the array.
• middle(arr): take in an array and return the middle-most element(s) of the given array.
• countLetters(str): returns how many times a letter appears in a string.,
• countOnly(arr, obj): returns how many times a value appears in an array.
• eqArrays(arr): returns true or false if two arrays are the same.
• eqObjects(obj): returns true or false if two objects are the same.
• findKey(obj, cb): takes in an object and a callback. Scans the object and returns the first key for which the callback returns a truthy value.
• findKeyByValue(objm str): finds the first key on an object where its value matches a given value.
• flatten(arr): take in an array, up to one nested arrays of elements, and returns a "flattened" version of the array.
• letterPositions(str): returns all the indices in a string where each character is found.
• map(arr, cb): takes two arguments, an array and a callback functions, and returns a new array based on the results of the callback function.
• takeUntil(arr, cb): takes two parameters, an array and a callback function, and returns a slice of the array with elements taken from the beginning. Continues until callback returns a truthy value.
• without(arr, itemToRemoveArr): returns a subset of a given array, removing unwanted elements.
