ES6是否可以使用花括号定义为两个或多个对象属性分配相同的值？

Question

I need to assign the same anonymous arrow function to two different properties of the same object, which is defined with curly braces . Eg now I have:

let testObject = {a: (a) => a+1, b: (a) => a+1};

And I want something like (pseudo-code):

let testObject = {a: b: (a) => a+1};

I actually know how to solve that problem (that is not a problem). But if there could be some way to assign the same intermediate (neither the variables, nor the primitives) values to two or more object properties like in a pseudo-code above, that would be very useful, isn't it?

Answer 1

No, not in the way you describe.

You could assign the function to a variable, but then it's not anonymous anymore:

const myFunc = a => a + 1;
const testObject = {a: myFunc, b: myFunc};

Answer 2

let testObject = (fn => ({a: fn, b: fn}))(a => a+1);
