get and set in TypeScript

Getting and Setting Values in TypeScript: Simplified!

Hey there! 😄 Welcome to our tech blog, where we break down complex problems into simple solutions. Today, we're diving into "get" and "set" methods in TypeScript. 🚀

Understanding the Problem

So, you want to create a "get" and "set" method for a property in TypeScript, but you're struggling with the syntax. Don't worry - we've got you covered! Let's break it down step by step. 👇

The code snippet you shared looks like this:

private _name: string;

Name() {
    get: {
        return this._name;
    }
    set: {
        this._name = ???;
    }
}

The issue here is that you're missing the correct syntax for setting a value. Let's solve that problem together! 💪

The "set" Keyword

To set a value using the "set" method, you need to define it within a function, just like the "get" method. Here's the correct syntax:

private _name: string;

get Name() {
    return this._name;
}

set Name(value: string) {
    this._name = value;
}

Notice the changes we made:

• We removed the parentheses after Name to transform it into a getter.

• We added a value parameter to the setter method, which represents the value you want to assign to _name.

Now, whenever you use the "set" method, you can pass a value to it:

this.Name = "John";

And when you access the "get" method, it will return the value you just set:

console.log(this.Name); // Output: John

Common Pitfalls and Tips

While using "get" and "set" methods, you might encounter a few common issues. Here are a couple of tips to help you avoid them:

1. Avoid Infinite Loops

Be careful not to inadvertently create infinite loops by calling the "get" or "set" method within themselves. This can lead to unexpected behavior and stack overflows. Always make sure to access the underlying backing field when using these methods.

2. Naming Conventions

In TypeScript, it's common to prefix private fields with an underscore _. By convention, the getter and setter methods have the same name as the property but without the underscore. This makes the code more readable and consistent.
