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 Andrey Li as part of my learnings at Lighthouse Labs.

Usage

Install it:

npm install @hanuz06/lotide

Require it:

const _ = require('@hanuz06/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• function1(assertArraysEqual(arr1, arr2)): Compares 2 arrays for whether they are identical or not.
• function2(assertEqual(actual, expected)): Takes 2 parameters, actual and expected values, and compares for whether actual value equals expected value.
• function3(assertObjectsEqual()): Takes 2 object parameters, actual and expected values, and compares for whether actual value equals expected value.
• function4(countLetters(str)): Takes a string and counts the number of each letters. An object is returned.
• function5(countOnly(allItems, itemsToCount)): Takes an array to lookthrough and an object an object specifying what to count. An object is returned.
• function6(eqArrays(arr1, arr2)): Takes 2 arrays and returns True if they are strictly identical, otherwise returns False.
• function7(eqObjects(object1, object2)): Takes 2 objects and returns True if both objects have identical keys with identical values, otherwise returns False.
• function8(findKey(obj, callback)): Takes an object and callback function to work on that object. Returned value: a string or undefined.
• function9(findKeyByValue(object, keySentence)): Takes an object and an object key, and finds a value of the object key. Returned value: a string or undefined.
• function10(flatten(array)): Takes a nested array and retuns a single level array.
• function11(head(array)): Takes an array and returns the 1st item.
• function12(letterPositions(string)): Takes a string sentence and returns an object of letters
• function13(map(array, callback)): Takes an array and a callback function to process that array, and returns a new array.
• function14(middle(array)): Takes an array and an array of middle item(s).
• function15(tail(array)): Takes an array, removes the 1st item, and returns the rest.
• function16(takeUntil(array, callback)): Takes an array and a callback function to process that array, and returns a new array.
• function17(without(array, itemsToRemove)): Takes 2 arrays. The 1st array is the array we remove items from, and the 2nd array contains items that needs to be removed in the 1st array. A new array is returned.
