Javascript/shorthand property names - およそMECEでないアカシックレコードの200那由多飛んで3万分の3

Javascript/shorthand property names

ES2015で作られた。

code:javascript

const a = "foo"

const b = 45

const c = {}

const obj = { a, b, c };

console.log(obj)

// Object { a: "foo", b: 45, c: Object { } }

既存の書き方では:

code:javascript

const a = "foo"

const b = 45

const c = {}

const obj = { a: a, b: b, c: c }

console.log(obj)

// Object { a: "foo", b: 45, c: Object { } }
