single try and multiple error handling in javascript

I’m Kailas, a passionate coder who started with PHP and WordPress in 2017 and now enjoys building scalable systems using Go, Node.js, AWS, Python, Redis, SQL, microservices, solving DSA in C++ and Python, and prototyping clean UI ideas in Figma before building.
Unlike java in javascript we have only single block to handle error
try {
// un-comment line below to see (reference error)
// show();
// un-comment line below to see (type error)
// a = "".toFixed()
} catch (e) {
if (e instanceof TypeError) {
// handle type error
console.log("You have type error");
}
else if (e instanceof ReferenceError) {
// handle reference error
console.log("You have reference error");
}
else{
console.log("other error")
}
}
