Invoke Method Inside Class JavaScript#
When working with classes in JavaScript, you might need to invoke a method inside the same class. There are different ways to do this, and we will explore some of them.
Using the 'this' keyword#
The 'this' keyword refers to the current object, which in this case is the class instance. You can use it to call methods inside the class.
Text
class MyClass {
myMethod() {
console.log('Hello from myMethod');
}
myOtherMethod() {
this.myMethod();
}
}
const myClass = new MyClass();
myClass.myOtherMethod(); // Output: "Hello from myMethod"
Using the class name#
You can also use the class name to call a method inside the class. This is useful when you need to call a static method.
Text
class MyClass {
static myStaticMethod() {
console.log('Hello from myStaticMethod');
}
myOtherMethod() {
MyClass.myStaticMethod();
}
}
MyClass.myStaticMethod(); // Output: "Hello from myStaticMethod"
const myClass = new MyClass();
myClass.myOtherMethod(); // Output: "Hello from myStaticMethod"
Using the super keyword#
The 'super' keyword is used to call a method from a parent class. This is useful when you have a subclass that overrides a method from the parent class but still needs to call the parent method.
Text
class ParentClass {
myMethod() {
console.log('Hello from ParentClass');
}
}
class ChildClass extends ParentClass {
myMethod() {
super.myMethod();
console.log('Hello from ChildClass');
}
}
const childClass = new ChildClass();
childClass.myMethod(); // Output: "Hello from ParentClass" "Hello from ChildClass"
