When an already-defined variable is given the same name within a new object, object-shorthand syntax is preferred as being more compact. Similarly, object-shorthand is also preferred for the definition of functions in object literals.
let a = 1; let myObj = { a : a, // Noncompliant fun: function () { // Noncompliant //... } }
let a = 1; let myObj = { a, fun () { //... } }
