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 @kennethz374/lotide

Require it:

const _ = require('@kennethz374f/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• head(Array): it only show the first element of the array.

• tail(Array): it slices out the first element of the array

• middle(Array): get the middle element in a array; if array length is even, it will return the middle two element of the array. if the array length is odd it will return the middle element of the array;if the array length is less than 2, it will return undefined,

• assertArraysEqual(actualArr,ExpectedArr): comparing whehter the acutal array and the expected array are identical, then print out a pass or fail message.

• eqArrays(Array1, Array2): comparing whether two arrays are identical

• assertEqual(actual, expected): comparing whether the actual value and the expected value are identical,then print out a pass or fail message.

• countLetters(String): count the total appearance of each letter and return an object with letter : times of occurance.

• countOnly(obj1, obj2): obj1 is the source and obj2 are the items that you want to count. it will return an object contains item name and numbe of its occurance;

• eqObjects(obj1,obj2): to determine whether two objects are identical

• findKey(obj1,callback): figure out the property name, can use callback to modified condition

• findKeyByValue(obj,value): figure out the property name, given the value of property

• flatten(Array): an array with other arrays inside, it can flatten it into a single-level array.

• letterPositions(String): when enter a string, it will return an object that shows the positon of each letter

• map(array,calback): map will loop through each element of the array and make modification with the callback function.

• takeUntil(array,callback): takeUntil will keep collecting items from a provided array until the callback provided returns a truthy value.

• without(ArrOfSrc,ArrOfRemove): This function should take in a source array and a itemsToRemove array. It should return a new array with only those elements from source that are not present in the itemsToRemove array

• assertObjectsEqual(actualObj,ExpectedObj): compare whether the acutal object and the expected object are identical, then print out a pass or fail message.
