When a Typescript object contains a key without a corresponding value, what is its significance?

In my experience, I've come across typescript objects that are defined in the following way:

        const MyObj = {
          myVar1,
          name1: myVar2
        }

Can someone explain the purpose of this object?

I know that there is a key-value pair with name1 as the key and myVar2 as the value. But what is the significance of having just a single value like myVar1?

(I've struggled to find a clear answer to this online)

Answer №1

This code snippet demonstrates the use of shorthand declaration in JavaScript. It involves defining a variable named myVar1 within an object named myObj, where the key will have the same name as the variable and its value will be equal to the variable itself.

In TypeScript, there are various shorthand techniques for creating objects. Another example is object deconstruction, which can be seen in the code snippet

const obj1 = {name: 'John'}; const obj2 = {...obj1}
. This creates a new object obj2 that inherits all the properties of obj1.
