I have code like this.

var key = anything;   

var object = {   

    key: key attribute  

};

I want to know if there is a way to replace that key with anything.

like

var object = {  

    anything: key attribute     

};

const key = anything;   



const object = {   

    [key]: key attribute

//  ^^^^^  COMPUTED PROPERTY NAME

};

Note the square brackets around key. You can actually specify any expression in the square brackets, not just a variable.
