Examples

Catching a SyntaxError

try {
  eval('hoo bar');
} catch (e) {
  console.error(e instanceof SyntaxError); 
  console.error(e.message);                
  console.error(e.name);                   
  console.error(e.fileName);               
  console.error(e.lineNumber);             
  console.error(e.columnNumber);           
  console.error(e.stack);                  
}

Creating a SyntaxError

try {
  throw new SyntaxError('Hello', 'someFile.js', 10);
} catch (e) {
  console.error(e instanceof SyntaxError); // true
  console.error(e.message);                // Hello
  console.error(e.name);                   // SyntaxError
  console.error(e.fileName);               // someFile.js
  console.error(e.lineNumber);             // 10
  console.error(e.columnNumber);           // 0
  console.error(e.stack);                  // @debugger eval code:3:9
}
