How to implement this in typescript?

Question

typescript

how to implement similar method call in typescript i get error
let p = new PacketWriter["writeVarInt"](0);

TS7053: Element implicitly has an 'any' type because expression of type '"writeVarInt"' can't be used to index type 'typeof PacketWriter'.
  Property 'writeVarInt' does not exist on type 'typeof PacketWriter'.

the method exists and is normally called like this, but I need to call my own class method for each argument and I want to do it without branching
let p = new PacketWriter.writeVarInt(0);

Answer 1

let p = new PacketWriter[method](0);
method must be constant
