Migration from Ethers V5 to V6

[SajjadReactDeveloper]

Hi, i have some code written in ethers v5 and i want to convert it to v6. How can i do that

1. const currentAllowance = BigNumber.from(
   await approvalTokenContract.allowance(
   user?.publicWalletAddress,
   paymentContractAddress
   )
   )

2. const maxApproval = BigNumber.from(2).pow(256).sub(1)

1. The value coming back from a contract should already be a BigInt in v6, so no need for conversion; you can just use it. :)
2. const maxApproval = (2n ** 256n) - 1n

Let me know if you still have any issues. :)
