Is it possible to use line breaks to differentiate properties?

The handbook addresses

The handbook states that you can separate properties using , or ;, and the last separator is optional in either case.

Is it possible to use line breaks to separate object properties like this? If so, where is this information documented?

interface Bar {
  x: number
  y: number
}

Answer №1

While not extensively documented, a comment on the microsoft/TypeScript#11856 repository suggests that TypeScript follows the same rules for automatic semicolon insertion as JavaScript. This means that if there is a newline followed by an unexpected token in your code, a semicolon will be inserted automatically. For example:

interface Foo {
  a: string
  b: string
}

is understood as

interface Foo {
  a: string;
  b: string
}

since

interface Foo { a: string b: string }
would result in a syntax error at b.
