Redefine Properties

Merge multiple objects' properties into target by redefining properties using extracted property descriptors.

• Works with multiple sources.
• Copies all own properties including nonenumerable ones.
• Uses Object.defineProperty for all properties.
• In case of conflict the last source of a property wins.

NB: Mutates the first argument!

Example

var redefine = require('redefine-properties');
 
var source = {
  get a() {
    return 42;
  }
};
var target = {};
 
redefine(target, source);
 
target.a === 42;
