JavaScript: Get/Set Prototype

Get Parent

You can use the following to get a object's parent:

• Reflect.getPrototypeOf → best way.
• Object.getPrototypeOf → implicitly convert arg to object type if not already.
• Object.prototype.__proto__ → hack. Not always work.

Set Parent

• Reflect.setPrototypeOf → best way.
• Object.setPrototypeOf → implicitly convert arg to object type if not already.
• Object.prototype.__proto__ → hack. Not always work.

WARNING: when you change a object X's parent, all X's children will be effected for property lookup, due to the Prototype Chain.
