How do I implement type constraints in my programming project?

To implement type constraints, you can use generics in languages like TypeScript or C#. This allows you to specify types for your functions or classes.

Can you give me an example in TypeScript?

Sure! Here's a simple example:

function identity<T>(arg: T): T {
    return arg;
}

This function uses a type parameter T to enforce type constraints.

What if I want to restrict the types to only numbers?

You can specify the type constraint like this:

function sum<T extends number>(a: T, b: T): T {
    return a + b;
}

This ensures that only numbers can be passed to the sum function.

Are there any limitations to using type constraints?

Yes, type constraints can make your code more complex and harder to read. It's important to balance type safety with code clarity.
