} catch (e) {
console.log(e instanceof SyntaxError); // true
console.log(e.message);
console.log(e.name); // "SyntaxError"
console.log(e.stack); // Stack of the error
}
Creating a SyntaxError
try {
throw new SyntaxError("Hello");
} catch (e) {
console.log(e instanceof SyntaxError); // true
console.log(e.message); // "Hello"
console.log(e.name); // "SyntaxError"
console.log(e.stack); // Stack of the error
