در تایپاسکریپت میتوان خروجی متدها و یا پارامترها را از چندین نوع مختلف، توسط مفهومی به نام union types معرفی کرد:
function printId(id: number | string) {
console.log("Your ID is: " + id);
} 
From this benchmark, we are able to understand that Rust has consistent performance and is almost always faster than C# and Go. But that is to be expected as Rust runs on the metal. Between C# and Go the performance seems to be nuanced. As C# and Go seems to outperform each other in difference scenarios.
