What is the "NEW " used for?

[Sairam002]

Hi guys,
So I'm in lesson-5 and I'm back with a new doubt.
In line number 9,10 and 22 of https://github.com/PatrickAlphaC/ethers-simple-storage-fcc/blob/main/deploy.js he kept a word new after the equal operator,

What does that means and when should we declare new?

Don't want to visit that page I got you, those 3 lines of code is bellow.

Code :-

let provider = new ethers.providers.JsonRpcProvider(process.env.RPC_URL);
let wallet = new ethers.Wallet(process.env.PRIVATE_KEY, provider);
const contractFactory = new ethers.ContractFactory(abi, binary, wallet);

I found answer in stack overflown https://stackoverflow.com/a/30478240 but I didn't understood what does the window object mean??

I'm facing some issue with opening the link please try to copy it and then paste. Sorry for the inconvenience..

The new Keyword says that you intaniate a new Object.
I guess the best way to explain it is to refer to this Video.
He explains the new Keyword and what does it mean.

Ethers allow you to create a provider to connect to your Blockchain, so you can instantiate a new provider with

new ethers.providers.JsonRpcProvider(process.env.RPC_URL);

and then you safe it your own declared variable

Do you need a Wallet, then make a new Wallet with new ethers.Wallet()
Do you need a XY, then make a new XY with new XY()
and so on

if you dont want to create something, because you just want something, like a string then you just call a function. f.e. LikeThis
