Remove property in Javascript

I have the following object

b.push({ data: d, width: 5, color: color });

then I have

b= [{data:10,width:5, color:"yellow"},{data:12,width:5, color:"red"},etc...];

I added color property and now I do not need and I want to remove it. I would like to know what is easiest way to do it?

Answer

You can delete it using delete

delete b[0].color
