JavaScript primarily has six basic data types: Number, String, Boolean, Undefined, Null, and Object. Additionally, ES6 introduced Symbol for unique identifiers, and ES2020 introduced BigInt for large integers. ECMAScript standards are crucial as they define the specifications for JavaScript. Key milestones include ES6 in 2015, which introduced major features like arrow functions, let/const, and classes. ES2017 brought in async/await for better asynchronous programming.

[@girdhar3224]

In JavaScript, let and const are two keywords that are used to declare variables. They were introduced in ES6 (2015) and provide block scope, which means that they are only accessible within the block in which they are declared. This is in contrast to the var keyword, which declares variables with function scope, meaning that they are accessible anywhere within the function in which they are declared.

[@ugyenofficial]

I just want to follow this teacher forever. ❤❤

JAVASCRIPT DAY 1.5 (DATATYPES AND ECMA STANDARD SUMMARY ) 1. Ecma standard = a standard for scripting languages. 2. Javascript has two version (before and after 2015). type "use strict"; at top of file for newer version of js. 3. Always think code readability.(write code with proper way ). Use mdn for documentation. 4. Data types in js : 1.string = "abcd" 2.number = numbers upto 2 ^ 53. 3.bigint = for bigger numbers. 4.boolean = true or false. 5.null = standalone value (type = object) 6.undefined = value not defined (type = undefined) 7.symbol = for unique value. 5. Console.log(typeof variable name) to check data types of a variable.

[@neutralengineer3873]

One suggestion and appreciation. Ye jo aap baar baar bolte hai na ki Aaj se 8-10 saal pahle javascript Aisa tha aur ab Aisa tha. Swarely it helps alot me. It makes my fundamentals more clearer by comparing javascript past and current chaal chalan.😊 So always try to explain Nirupa Roy Javascript and Rakhi Sawant Javascript. It will help experience developer like me who is working on since years but fundamentals are weak. It helping me alot. Good teaching Bro.

[@gujarIsBack-b2c]

i know in solved the problem but in simple way to use like console.table in our my mind to make an object to set properties different type and iterate loop to check every property case .. but you know very well JavaScript that's why I'm raised an question please answer me any simple way one way in my mind i explain you in any other way very easy to check types every property ?? .... My Solution const obj = { property1: 42, property2: "Hello, World!", property3: [1, 2, 3], property4: { key: 'value' } }; for (const key in obj) { console.log(`${key}: ${typeof obj[key]}`); } This code will loop through each property in the obj object and log the property name and its typeof value one by one.
