What are namedAccounts?

I'm a little bit confused about the below code. Can someone explain to me the below code, in the deployer object first we have default key and it has 0 value second we have 1 key and it has 0 value so these values and keys are confusing for me.

namedAccounts: {
        deployer: {
            default: 0, // here this will by default take the first account as deployer
            1: 0, // similarly on mainnet it will take the first account as deployer. Note though that depending on how hardhat network are configured, the account 0 on one network can be different than on another
        },
    },

@shakilkhan12 :

default: 0 means the, Account : 0 from the hardhat node is deployer's account in your local deployment.

And, 1: 0 means that, on the mainnet deployment the first account from your wallet will be the the deployer's account.

In 1:0,1 represent mainnet?
