Javascript objects encapsulate an idea into an easy-to-manipulate digital object. Javascript Object Constructors Step-by-Step This blog post will explore how the Javascript standard directs Javascript ES6 programmers to create object constructors. In JavaScript, an object can be created in two ways: 1) using Object Literal/Initializer Syntax 2) using the Object() Constructor function with the new keyword. (Before moving on, it might be worthwhile reviewing our blog entry on Javascript prototypes, the backbone of objects.) These initializations are bundled together in special functions called constructors. The act of creating an object includes initializing its internal state, like the color of a bicycle object. These are essential to creating robust and maintainable software because they create a convenient “thing” that maps directly to the data and actions essential to the problem being solved, hide private internal working parts, and provide a conceptual framework that makes it easier to understand its operations. It isn’t required, so consider it supplemental.All Javascript types are based internally on objects. This section contains helpful links to other content.
