Typescript Object 的类型未知

Question

How to define the data type of value in the nodejs function written in typescript, so that error of Object is of type unknow can be solved?

Answer 1

You need to implement type for value. Try smth like this:

type valueType = {
  id: string,
  field1: number,
  field2: string,
}

const obj = {
  a: {
    id: '12',
    field1: 1,
    field2: 'asdas',
  }
}

for (const [key, value] of Object.entries(obj)) {
  const typedValue: valueType = value;
}
