Get an object property name as string

Question

Is it possible to get the property names of an object as an array of strings?

For example if I made the object:

var obj = {
 prop1: true,
 prop2: false,
 prop3: false
}

s there a some method 'getPropNames(obj)' that would return an array where each element is a property name so it would look like this:

props[0] = "prop1" 
props[1] = "prop2" 
props[2] = "prop3" 

Thanks in advance for any help.

Answer 1

You're looking for Object.keys(obj)

Answer 2

You can try this too.

function  getPropName(obj) {
    var propNameArray= [];
    for (var propertyName in obj) {
      propNameArray.push(propertyName);
      }
    console.log(propNameArray);
  }
