How to use the change-case.upperCase function in change-case

function currentLayer(newLayerName, layerName) {
  // UpperCase
  let name = newLayerName.replace(/%\*u%/gi, changeCase.upperCase(layerName))

  // LowerCase
  name = name.replace(/%\*l%/gi, changeCase.lowerCase(layerName))

  // Title Case
  name = name.replace(/%\*t%/gi, toTitleCase(layerName))
  // name = name.replace(/%\*t%/gi, changeCase.titleCase(layerName))

  // UpperCase First
  name = name.replace(/%\*uf%/gi, changeCase.upperCaseFirst(layerName))

  // Camel Case
  name = name.replace(/%\*c%/gi, changeCase.camelCase(layerName))

  // Layername
  name = name.replace(/%\*/g, layerName)

function currentLayer(newLayerName, layerName) {
  // UpperCase
  let name = newLayerName.replace(/%\*u%/gi, changeCase.upperCase(layerName));

  // LowerCase
  name = name.replace(/%\*l%/gi, changeCase.lowerCase(layerName));

  // Title Case
  name = name.replace(/%\*t%/gi, toTitleCase(layerName));
  // name = name.replace(/%\*t%/gi, changeCase.titleCase(layerName))

  // UpperCase First
  name = name.replace(/%\*uf%/gi, changeCase.upperCaseFirst(layerName));

  // Camel Case
  name = name.replace(/%\*c%/gi, changeCase.camelCase(layerName));

  // Layername
  name = name.replace(/%\*/g, layerName);
