How can I prevent runtime errors in JavaScript?

What are some common runtime errors in JavaScript?

Common runtime errors include TypeErrors, ReferenceErrors, and SyntaxErrors. They often occur due to undefined variables or incorrect function calls.

How can I avoid these errors in my code?

You can avoid runtime errors by using strict mode, validating inputs, and implementing error handling with try-catch blocks.

What is strict mode and how does it help?

Strict mode is a way to opt in to a restricted variant of JavaScript. It helps catch common coding mistakes and prevents the use of certain features.

Can you give me an example of using try-catch?

Sure! Here's a simple example:

try {
    let result = riskyFunction();
} catch (error) {
    console.error('Error occurred:', error);
}
