How to print a message in error handling with try-catch with JavaScript?
To print a message in error handling with try-catch with JavaScript, we can log the stack, name and message properties.
For instance, we write:
const x = {
asd: "asd",
};
try {
JSON.parse(x);
} catch (e) {
console.log("Error", e.stack);
console.log("Error", e.name);
console.log("Error", e.message);
}
The stack property has the stack trace string.
name has the error name as a string.
And message has the error message as a string.
Therefore, we should see 'Error SyntaxError' and 'Error Unexpected token o in JSON at position 1' logged respectively for e.name and e.message.
