var obj = {[id:1,status:false],{id:2,status:false}}

Is there any way I can change the 1st status from false to true directly?Thanks. :-)

Sure:

obj[0].status = true; // obj[0] takes the first element of the array.
if this does not work than try:
obj[0] = {id:1, status: true}; // check if this changes the value.

@dobrienlzd Thanks for your reply.
Actually, I want to change the attribute in setState method;

this.setState( //Change attribute value directly here )

AFAIK,there are 2 way to do this:

  1. Object.assign();
  2. React.addons.update();

But I can not figure out how to use this.any idea about that? thank u.
