Ecma262: Auto object destructuring

[AlexSHoffman]

Let's say we have data object someDescriptiveName and we need to destructure it multiple times in different functions with the purpose of being able to use shorter property names.

For example:

property1 Instead of this.someDescriptiveName.property1

Data

someDescriptiveName: {
  property1: false,
  property2: false,
  property3: false,
  property4: false,
  property5: false,
}

Current method

function func1() {
  let {
    property1,
    property2,
    property3,
    property4,
    property5,
  } = this.someDescriptiveName
  console.log(property1)
}

function func2() {
  let {
    property1,
    property2,
    property3,
    property4,
    property5,
  } = this.someDescriptiveName
  console.log(property1)
}

Proposed method

function func1() {
  let {*} = this.someDescriptiveName
  console.log(property1)
}

function func2() {
  let {*} = this.someDescriptiveName
  console.log(property1)
}

@AlexSHoffman This exists: it’s the with statement. It’s disallowed in strict mode because it leads to a variety of problems.
