Instantiating Objects
Explore how to create objects in JavaScript using different instantiation methods including constructors and object literals. Understand the challenges of method duplication and how to improve efficiency by managing method definitions. Gain foundational knowledge to write cleaner and more maintainable JavaScript code before advancing to prototypes.
We'll cover the following...
In most programming languages, constructors are the only way to instantiate new objects. As you already saw in the introduction of this section, JavaScript allows you to use manual setup and you can create objects using the object literal (JSON). The most concise way is by using the object literal; it is easy to read and helps you use less characters when typing.
However, it has a significant issue. You can only instantiate your objects one by one, and you must repeat the literal every time, often including dozens of lines. ...
