Errors are an inevitable part of programming, and JavaScript is no exception. Whether you’re a seasoned developer or just starting out, understanding how to handle errors effectively is crucial for writing robust and reliable code.

In this guide, we’ll take you through the basics of error handling in JavaScript, providing clear explanations and practical examples along the way.

Understanding Errors in JavaScript

Before diving into error handling, it’s essential to understand the types of errors you might encounter in JavaScript. Errors in JavaScript can broadly be categorized into two types: syntax errors and runtime errors.

Syntax errors occur when you write code that violates the rules of the JavaScript language. These errors are typically detected by the JavaScript engine during the parsing phase, before the code is executed. Common examples of syntax errors include missing parentheses, misplaced semicolons, or undefined variables.

// Syntax Error: Missing closing parenthesis
function greet(name {
    console.log(`Hello, ${name}`);
}
