Functions

OmitThisParameter

Removes an explicit `this` parameter from a function type.

What it is

The type-level shape of binding a method to its receiver. Ordinary parameters and the result remain, while the special `this` requirement disappears. That is the signature a caller can invoke without using `.call`, `.apply`, or method syntax.

Examples

```
OmitThisParameter<typeof formatHex>
```
→(prefix: string) => string

Parameters<OmitThisParameter<typeof formatHex>>

→[prefix: string]

```
ThisParameterType<OmitThisParameter<typeof formatHex>>
```
→unknown
Extracting `this` afterwards proves that the special parameter is gone.

Each resolved type above was printed by TypeScript 6.0.3, not written by hand.

What it does not do

It changes only the type. It does not bind a function at run time; use `.bind(receiver)` to create the corresponding value.
For generic or overloaded functions the standard definition cannot preserve every signature; generics are erased and the last overload wins.

Takeaway

`OmitThisParameter<T>` describes the callable type left after the receiver has already been supplied.
