Did you know that if you create a trailing variable led by the spread operator in TypeScript object destructuring that everything you didn't pull out in the other variables ends up in the new, watered-down variable?

Consider:

var hogwash = {
   foo: 13,
   bar: 42,
   baz: 69,
   qux: 86
};
const { bar, baz, ...malarkey } = hogwash;
console.log(bar);
console.log(baz);
console.log(malarkey);

 
 

The following will be logged:

• 42
• 69
• {
     foo: 13,
     qux: 86
  }
