Syntax Error

What This Error Means

This error occurs when the JavaScript interpreter encounters a syntax mismatch, specifically when trying to use the 'export' keyword within a class declaration.

Why It Happens

In JavaScript, the 'export' keyword can only be used outside of a class declaration or outside of any function declaration. When it's used inside a class, it throws a syntax error because JavaScript is expecting the class to be a part of a larger module declaration, not a standalone class.

How to Fix It

1. 1To fix this error, move the 'export' keyword outside of the class declaration. If you're trying to export a class, use the 'export default' syntax or 'export { MyClass }' syntax instead. Here's an example:
2. 2// Before (broken code)
3. 3export class MyClass {
4. 4 constructor() {
5. 5 console.log('Hello');
6. 6 }
7. 7}
8. 8// After (fixed code)
9. 9export default class MyClass {
10. 10 constructor() {
11. 11 console.log('Hello');
12. 12 }
13. 13}

Example Code Solution

export class MyClass {
  constructor() {
    console.log('Hello');
  }
}

export default class MyClass {
  constructor() {
    console.log('Hello');
  }
}
