How to solve Mexican wave algorithm in JavaScript

The Mexican Wave
The wave (known as the Mexican wave in the English-speaking world outside North America) is an example of metachronal rhythm achieved in a packed stadium when successive groups of spectators briefly stand, yell, and raise their arms. Immediately upon stretching to full height, the spectator returns to the usual seated position.

The result is a wave of standing spectators that travels through the crowd, even though individual spectators never move away from their seats. In many large arenas the crowd is seated in a contiguous circuit all the way around the sport field, and so the wave is able to travel continuously around the arena; in discontinuous seating arrangements, the wave can instead reflect back and forth through the crowd. When the gap in seating is narrow, the wave can sometimes pass through it. Usually only one wave crest will be present at any given time in an arena, although simultaneous, counter-rotating waves have been produced. (Source Wikipedia)

Task
Your task is to create a function that turns a string into a Mexican Wave. You will be passed a string and you must return that string in an array where an uppercase letter is a person standing up.

Solution
Before diving into coding make sure to understand the problem and visualize the solution in form of pseudo code, break it down into steps.

Steps

Create an array to store the results
return empty array if the string is empty
Loop through the letters in the string
Make a copy of the string to an array
if there is a space in the string skip that space,
Covert each letter of the copied string array to uppercase then join them together as one string
then push them to our result array and finally return the result array.

const wave=(str)=>{
   let result = [];
   if([...str].length === 0) return [];
   for(let i = 0; i < str.length; i++){
       let copy = str.split('');
       if(copy[i] === ' ') continue;
       copy[i] = copy[i].toUpperCase('');
       result.push(copy.join(''))
   }
   return result
}
console.log(wave('two words'))
/* ["Two words", "tWo words", "twO words", "two Words", "two wOrds", "two woRds", "two worDs", "two wordS"]; */

How to use ES6 import in Node Project

ES6 Module

A file containing reusable code is known as a module. Whether or not it is declared, the import modules are in strict mode.
Modules that are exported by another module are imported using the import statement.

How to use import Syntax:

import name from 'module-name'

Importing an entire module:

import * as name from 'module-name'

Import default export from a module:

import name from 'module-name'

Importing a single export from a module:

import { name } from 'module-name'

Importing multiple exports from a module:

import { nameOne , nameTwo } from 'module-name'

Importing a module for side effects only

import './module-name'

Exporting a module

export default module_name

Node JS does not directly support ES6 import. If we attempt to utilize node js import function to directly import modules, an error will be generated. For instance, Node JS would raise the following error if we attempt to import the express module by writing import express from "express".

ES modules are experimentally supported by Node. We must make some adjustments to the package.json file in order to enable them. Make sure Node is installed before continuing with the instructions. The steps to do so are shown below.

Add "type": "module" to the package.json file. This is added to enable ES6 modules.
This is how the package.json file should appear:

//package.json { "name": "index", "version": "1.0.0", "description": "", "main": "index.js", "type": "module", "scripts": { "test": "echo \"Error: no test specified\" && exit 1" }, "keywords": [], "author": "", "license": "ISC" }

Make a file called index.js, and then use ES6 import to write your program. Let's try importing Express in the index.js file as an example.

//index.js

import express from 'express';

const app = express();

app.get('/', async(req,res) => {
res.send('It is working');
})

const PORT = 5000;

app.listen(PORT,() => {
console.log(Running on PORT ${PORT});
})

Another method of utilizing the esm module is to create a different file, such as server.js, which loads esm prior to the application itself. Write the following code in the server.js file.

//server.js require = require("esm")(module); module.exports = require("./index.js");

We are importing the index.js file, which contains the actual program that has to be run, into the server.js file.

To run the program, type node server.js into the terminal.

Getting started with linked list

Davidalimazo — Mon, 11 Jul 2022 07:15:18 +0000

A linked list is a linear data structure, in which the elements are not stored at contiguous memory locations. The elements in a linked list are linked using pointers as shown in the image above.
In simple terms, a linked list consists of nodes where each node contains a data field and a reference to the next node in the list. the linked list is way different from the array data structures because in linked list the list only knows about the head and tail node while each element only knows about the next element after them.

Implementation of LinkedList in Javascript

We are going to implement append: to add values at the end of the list, prepend: to add values at the beginning of the list, find value: to search the list for a particular value, delete: to remove a value from the list, insert after: to insert a value just after a specified value, print values: to view all the values of the linked list.

insert after and print all values

thanks for your time, I have more post liked this to help you understand data structures, please keep checking.
