waht is the meaning of <> " angular bracket" in javascript : I using vscode for javascript. for example when i writing a filter on an array vscode shows me this documentation for callback function:

>"< S extends T >(callbackfn: (value: T, index: number, array: readonly T[]) => value is S, thisArg?: any): S[]
"



i see <> in typescript code but can't understand concept of it.
what does that angular brackets means?
