convert all keys of object to variable in ReactJS

Question

In react you can do something like

const obj = { thing: 'a', }

then const { thing } = obj is a shorthand for const thing = obj.thing

is there a way to convert all object key/value pairs at once?

Object.keys(obj).map((key) => { const eval(key) = obj[key]; }

something like that.

Thanks in advance!

The only way to do it is by destructuring the object, but you will need to know your object properties for that:

const { prop1, prop2, prop3 } = obj;

And by the way your example with ".map" won't work because you are creating a local constants which won't be accessible outside that function.

To add to this you can destruct an object of an object like so: const { prop1: { prop2 }} = obj; would output prop2.
