For example, if the current network is Rinkeby, I need the string "rinkeby".

You can check the current network chain ID like this:

console.log(window.ethereum.networkVersion, 'window.ethereum.networkVersion');

And these are the chain IDs for the most used ethereum networks:

typeof window.ethereum.networkVersion is string.

I never said it's not a string, it's the network ID represented as string.

Is there a place I can find all chain ids ? Lets say if I want to know the chain id of matic main chain, where should I check. Sorry if this is a dumb question. Newbie here !

@TheEhsanSarshar very important note, thank you! Because when you listen to the chainChanged event it returns a number.
