What are getters and setters?
How to create Getters and Setters?
There are three following ways to create Getters and setters.
- Using the get and set keywords
- Using the Object.defineProperty() method
- Using the default getter and setter methods, also known as the default method syntax
Here, we are discussing the get and set keyword method only.
The get and set keywords
As the title indicates, the getter and setter variables start with a ‘get’ and ‘set,’ and the variable follows with a capital letter. In simple words, get means to define a getter property to get a property’s value rather than the method. Its name has to be different than the data property in which that value to be accessed is stored. While using getters and setters in website development, you must note that the old Internet Explorers (IE8) do not support the get keywords.
However, the setter defines a setter method to set the value of a property. For setters, the same names can be used as the getters along with some parameters. These parameters allow passing the new values towards the properties.
Using the get and set keywords, you will have an advantage in website development. As the names for getters and setters are different, you won’t mix them with data properties’ values. Moreover, if you use the get and set keywords, you will be able to keep your data properties private.
