Syntax help

variable declaration

Keyword	Description	Scope
var	Var is used to declare variables(old way of declaring variables)	Function or global scope
let	let is also used to declare variables(new way)	Global or block Scope
const	const is used to declare const values. Once the value is assigned, it can not be modified	Global or block Scope

Backtick Strings

Interpolation

Multi line Strings

Arrays

An array is a collection of items or values.

Syntax:

let arrayName = [value1, value2. etc]; // or let arrayName = new Array("value1","value2". etc);

Example:

let mobiles = ["iPhone", "Samsung", "Pixel"]; // accessing an array console.log(mobiles[0]); // changing an array element mobiles[3] = "Nokia";

Arrow functions

Arrow Functions helps developers to write code in concise way, it’s introduced in ES6.
Arrow functions can be written in multiple ways. Below are couple of ways to use arrow function but it can be written in many other ways as well.

Syntax:

Example:

const numbers = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] const squaresOfEvenNumbers = numbers.filter(ele => ele % 2 == 0) .map(ele => ele ** 2); console.log(squaresOfEvenNumbers);

De-structuring

Arrays

let [firstName, lastName] = ['Foo', 'Bar']

Objects

rest(. ) operator

Spread(. ) operator

//Object spread const post = < . options, type: "new" >//array spread const users = [ . adminUsers, . normalUsers ]

Functions

function greetings( < name = 'Foo' >= <>) < //Defaulting name to Foo console.log(`Hello $!`); > greet() // Hello Foo greet(< name: 'Bar' >) // Hi Bar

Loops

1. If:

IF is used to execute a block of code based on a condition.

Syntax

2. If-Else:

Else part is used to execute the block of code when the condition fails.

Syntax

3. Switch:

Switch is used to replace nested If-Else statements.

Syntax

4. For

For loop is used to iterate a set of statements based on a condition.

for(Initialization; Condition; Increment/decrement) < //code >

5. While

While is also used to iterate a set of statements based on a condition. Usually while is preferred when number of iterations are not known in advance.

6. Do-While

Do-while is also used to iterate a set of statements based on a condition. It is mostly used when you need to execute the statements atleast once.

Classes

ES6 introduced classes along with OOPS concepts in JS. Class is similar to a function which you can think like kind of template which will get called when ever you initialize class.

Syntax:

class className < constructor() < . >//Mandatory Class method method1() < . >method2() < . >. >

Example:

class Mobile < constructor(model) < this.name = model; >> mbl = new Mobile("iPhone");

Reviews

At first I didnt quite understand the value of this deal, so took it for a spin, and I immediately got hooked 🙂 let me just start by saying this is SOOOO super sleek!! Ran a few bugs intentionally and was shown an immediate and exact description of the bug that I had created. The debug feature is worth the price alone! Then I spun up a react project within seconds, (spun up meaning I clicked a button!) and a live preview was INSTANTLY there! no npm run start or anything. and there is virtually any hot frontend framework you can think of vue.js 3 is there! and a whole range of css frameworks including my personal favorite: tailwind css. super pleased.

I use this for learning and testing various web technologies. Gone is the time spent setting everything up, I also get an instant live preview of my work coupled with a useful console. I work with tailwindcss, alpinejs, bootstrap and I can easily explore other technologies. The author is responsive and maintains the application. I requested some frameworks, these were subsequently added. I am glad to have this tool in my arsenal as it changes the way I now work on the web.

I need a central (online) to try out code and test new ideas out. PlayCode is simple to use, elegant, and seems to have covered all the main frameworks and libraries.
