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 @jelywrig/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(actual, expected): console logs: pass if arrays equal, fail if not equal
• assertEqual(actual, expected): console logs strict equality assertion of values passed
• assertObjectsEqual(actual, expected): console logs: pass if objects equal, fail if not equal
• countLetters(string): given a string returns character account excluding spaces
• countOnly(allItems, itemsToCount): given array of values and object of values to count returns object with counts of values to be counted
• eqArrays(actual, expected): given two arrays returns true if equal. Supports nested arrays. Does not support objects as values.
• eqObjects(actual, expected): given two objects returns true if equal. Supports nested objects.
• flatten(array): given an arbitrarily nested array returns values in single 'flat' array
• head(array): returns first element of array
• letterPositions(string): given a string returns object with letters as keys and arrays of indices as values
• map(array, callback): returns new array of values as modified from original array by callback function
• middle(array): returns new array which represents middle of array passed (returns empty array for array with length <=2, returns array with 1 val for odd length, 2 val for even length )
• tail(array): returns new array with all but first element of array
• takeUntil(array, callback): returns new array with all values from original array taken until callback returns true
• without(source, itemsToRemove): returns new array with content of source without the values defined in itemsToRemove
