change property name

Question

I have a JavaScript object as follows:

var a = { Prop1: \'test\', Prop2: \'test2\' }

How would I change the \"property name\" of Prop1 to P

Workaround

Convert your Object to a String using JSON.stringify, then replace any occurrences of Prop1 with Prop3 using str.replace("Prop1", "Prop3"). Finally, convert your string back to an Object using JSON.parse(str).

Note: str.replace("Prop1", "Prop3") will only replace the first occurrence of "Prop1" in the JSON string. To replace multiple, use this regex syntax instead: str.replace(/Prop1/g, "Prop3") Refrence Here

Example

var a  = { Prop1: 'test', Prop2: 'test2' }
str = JSON.stringify(a);
str = str.replace("Prop1","Prop3");
var converted  = JSON.parse(str);
