How can I use JSDoc for type safety in my JavaScript projects?

You can use JSDoc to add type annotations to your JavaScript code, which helps with type safety. For example, you can define a function like this:

/**
 * Adds two numbers.
 * @param {number} a - The first number.
 * @param {number} b - The second number.
 * @returns {number} The sum of the two numbers.
 */
function add(a, b) {
    return a + b;
}

What are the benefits of using JSDoc for type safety?

Using JSDoc improves code readability, helps with IDE autocompletion, and catches type errors during development.

Can JSDoc work with TypeScript?

Yes, JSDoc can be used in TypeScript projects to provide additional type information, but TypeScript's own type system is generally preferred.

Are there any tools that can help with JSDoc?

Yes, tools like JSDoc itself can generate documentation from your comments, and TypeScript can also check types based on JSDoc annotations.
