Generic Functions

Some functions in the script reference (for example, the various GetComponent functions) are listed with a variant that has a letter T or a type name in angle brackets after the function name:

//C#
void FuncName<T>();
//JS
function FuncName.<T>(): T;

These are known as generic functions. The significance they have for scripting is that you get to specify the types of parameters and/or the return type when you call the function. In JavaScript, this can be used to get around the limitations of dynamic typing:-

// The type is correctly inferred since it is defined in the function call.
//In C#
var obj = GetComponent<Rigidbody>();
//In JS
var obj = GetComponent.<Rigidbody>();

In C#, it can save a lot of keystrokes and casts:

Rigidbody rb = go.GetComponent<Rigidbody>();

// ...as compared with:

Rigidbody rb = (Rigidbody) go.GetComponent(typeof(Rigidbody));

Any function that has a generic variant listed on its script reference page will allow this special calling syntax.
