βœ… Viability Checklist

My suggestion meets these guidelines:

  • This wouldn't be a breaking change in existing TypeScript/JavaScript code
  • This wouldn't change the runtime behavior of existing JavaScript code
  • This could be implemented without emitting different JS based on the types of the expressions
  • This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, new syntax sugar for JS, etc.)
  • This feature would agree with the rest of TypeScript's Design Goals.

⭐ Suggestion

We have:

{} is missing the following properties from type {} and {} more.

It's helpful to add all missing attributes/properties by quickfix. the default value could be null/undefined/zero-value/etc.

πŸ“ƒ Motivating Example

interface Foo {
  a: string
  b: number
}

const f: Foo = {}
--------------------------------
         ^ missing a, b
-------------------------------

To:

interface Foo {
  a: string
  b: number
}

const f: Foo = {
 a: undefined,
 b: undefined
}
