Imagine having a class with two methods declared for exclusive use within that class.
// 1.
private get something() { return 0; }
// 2.
private getSomething() { return 0; }
While I am familiar with getters and setters, I'm intrigued to know if there is any distinction in this scenario.
The distinction lies in the syntax utilized to retrieve the value
class Example {
private get someValue() { return 0; }
private getSomeValue() { return 0; }
public performAction(){
console.log(this.someValue); // calls the specified getter method but resembles a field rather than a method call
console.log(this.getSomeValue())
}
}
Furthermore, the get/set syntax is essentially shorthand for Object.defineProperty.
