How to use the @webassemblyjs/helper-wasm-bytecode.globalTypesByString function in @webassemblyjs/helper-wasm-bytecode

export function encodeMutability(v) {
  var byte = constants.globalTypesByString[v];

  if (typeof byte === "undefined") {
    throw new Error("Unknown mutability: " + v);
  }

  return parseInt(byte, 10);
}
export function encodeUTF8Vec(str) {

export function encodeMutability(v) {
  var byte = constants.globalTypesByString[v];

  if (typeof byte === "undefined") {
    throw new Error("Unknown mutability: " + v);
  }

  return parseInt(byte, 10);
}
export function encodeUTF8Vec(str) {

export function encodeMutability(v: Mutability): Byte {
  const byte = constants.globalTypesByString[v];

  if (typeof byte === "undefined") {
    throw new Error("Unknown mutability: " + v);
  }

  return parseInt(byte, 10);
