2. JavaScript syntax

The syntax of the JavaScript programming language is the set of rules that defines how a JavaScript program will be written and interpreted (by both the runtime system and by human readers).

3. Data Types and Variables

JavaScript is dynamically typed (also called loosely typed) scripting language. That is, in javascript variables can receive different data types over time. Datatypes are basically typed of data that can be used and manipulated in a program.

BigInt 1/3

BigInt:

In JavaScript, we have a BigInt data type in which we can assign the integer of arbitrary length to an integer.

We can create BigInt by placing the n at the end of the integer or we can simply call the BigInt() function that creates an integer of arbitrary length from a string.


              123456789
            
let bigint = 123456789n;
console.log(bigint);

let bigintFromString = BigInt("123456789");
let bigintFromInteger = BigInt(123456789);

console.log(bigint);
console.log(bigintFromString);
console.log(bigintFromInteger);
