Remove property in Javascript [duplicate]

Question

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 1

You can delete it using delete

delete b[0].color 

Answer 2

If you're using .push({}) and pushing an object literal and not having reference any other way to those objects just use map:

b = b.map(function(obj) {   return {data: obj.data, width: obj.width}; }); 

If you happen to have reference then the only way I can really think of it would be to use the delete keyword even though I don't recommend it:

for(var obj of b) {   delete obj.color; }
