factory vs constructor

Benchmark created by Matt Baker on

Description

When instantiating objects of the same class, is it faster to use the new keyword or just object literals?

Setup

function TestConstructor() {
      this.test = true;
      this.person = 'Matt';
      this.number = 9000;
    }
    
    function testFactory() {
      return {
        test: true,
        animal: 'monkey',
        number: 8000
      };
    }
