How to fight tons of unresolved variables warning in WebStorm?

Question

I have a function that takes data from server:

function getData(data){
    console.log(data.someVar);
}

WebStorm says that someVar

Answer 1

All other answers are incorrect for the general case. What if you don't get data as a parameter? You don't have JSDoc then:

function niceApiCall(parameters) {
  const result = await ...  // HTTP call to the API here
  for (const e of result.entries) {
    .. // decorate each entry in the result
  }
  return result;
}

WebStorm will warn that "result.entries" is an unresolved variable (field).

The general solution is to add an @namespace declaration:

function niceApiCall(parameters) {
  /** @namespace result.entries **/
  const result = await ...  // HTTP call to the API here
  for (const e of result.entries) {
    .. // decorate each entry in the result
  }
  return result;
}
