ethers.toBigInt(...).eq is not a function

Question

I’m using ethers v6 and comparing the converted numbers, but I’m facing this error:

TypeError: ethers.toBigInt(...).eq is not a function

Answer 1

In ethers v6, instead of eq you’ve to use the == operator for equality comparison, like:

value1 = ethers.toBigInt("1000");
value2 = ethers.toBigInt("1000");
isEqual = (value1 == value2);

You can refer to the Big Numbers migration section of the ethers v6 doc.

Answer 2

I think You need to try the ether.js 5.7.2 version as it is stable and works.
