How to set initial properties to a JavaScript class
Solution
To set initial properties to a JavaScript class, follow these steps:
-
Define the class using the
classkeyword. For example,class MyClass { }. -
Inside the class, create a constructor method using the
constructorkeyword. This method will be called when an instance of the class is created. For example,constructor() { }. -
Inside the constructor method, use the
thiskeyword to refer to the current instance of the class. Assign initial values to the properties of the class using the dot notation. For example,this.propertyName = value;. -
Repeat step 3 for each property you want to set an initial value for.
Here's an example of setting initial properties to a JavaScript class:
class MyClass {
constructor() {
this.property1 = "initial value 1";
this.property2 = "initial value 2";
}
}
In this example, the MyClass class has two properties, property1 and property2, which are assigned initial values of "initial value 1" and "initial value 2" respectively.
