How to Use Throw in JavaScript If Statements?

Estimated read time 1 min read

In JavaScript, the throw statement is used to throw an exception. An exception is a signal that an error has occurred in your code. When an exception is thrown, the code execution stops and control is transferred to the nearest catch block. Here’s how you can use throw in an if statement:

if (condition) {
  throw new Error("Error message");

The Error object is a built-in error object in JavaScript. You can also throw any other value or custom object as an exception:

if (condition) {
  throw "Error message";

You can catch the exception using a try...catch block:

try {
  // code that might throw an exception
} catch (error) {
  // code to handle the exception

The error object in the catch block contains information about the exception that was thrown.
