Abstraction in computer programming is a way to reduce complexity and allow efficient design and implementation in complex software systems. It hides the technical complexity of systems behind simpler APIs.
Advantages of Data Abstraction
- Helps the user to avoid writing low level code.
- Avoids code duplication and increases reusability.
- Can change internal implementation of class independently without affecting the user.
- Helps to increase security of an application or program as only important details are provided to the user.
Example
class ImplementAbstraction { // method to set values of internal members set(x, y) { this.a = x; this.b = y; } display() { console.log('a = ' + this.a); console.log('b = ' + this.b); } } const obj = new ImplementAbstraction(); obj.set(10, 20); obj.display(); // a = 10 // b = 20
