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 @username/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(actual, expected): Assertion function that determines if two arrays are identical
• assertEqual(actual, expected): Assertion function that determines if two values are identical
• assertObjectsEqual(actual, expected): Assertion function that determines if two objects are identical
• countLetters(string): Counts the characters in the specified string ignoring spaces
• countOnly(allItems, itemsToCount): Counts occurences of a given list of items
• eqArrays(array1, array2): Determines if two arrays are identical and returns true/false based on the outcome
• eqObjects(object1, object2): Determines if two objects are identical and returns true/false based on the outcome
• findKeyByValue(object, value): Finds the first key in an object that matches the specified value
• findKey(object, callback): Finds the first key in an object for which the given callback function returns true
• flatten(array): Flattens an array containing other arrays into one array
• head(array): Returns the first object in an array
• letterPositions(string): Counts each occurence of each non-space character in a string and returns an array containing the index at which each character was found
• map(array, callback): Iterates over an array executing a callback function on each element and returns an array containing all elements for which the callback returned true.
• middle(array): Returns the middle element(s) of an array
• tail(array): Returns the last element of an array
• takeUntil(array, callback): Returns each element of an array before an element for which the callback function returns false is encountered.
• without(array1, array2): Returns a new array containing all elements of array 1 that are not present in array 2
