期望一个赋值或函数调用，而是在定义接口时看到一个表达式

Question

Im trying to build a form and start by defining an interface

 interface TokenListProps { readonly contractAddress: string; }

and I get a compile error 'Expected an assignment or function call and instead saw an expression' for this line.

Any suggestions on why this might be?

Answer 1

Based upon the info you have provided the issue is the newlines in your definitions.

You currently have this:

interface
TokenListProps
{
  readonly
  contractAddress: string;
}

And it should be like this:

interface TokenListProps
{
  readonly contractAddress: string;
}
