Platform.isLinux and company should be const #35705
Description
We'd like to have code that does something like this:
// these are giant maps
const Map mac = {...};
const Map windows = {...};
const Map linux = {...};
convert(foo) {
if (Platform.isMac)
return mac[foo];
if (Platform.isLinux)
return linux[foo];
if (Platform.isWindows)
return windows[foo];
return null;
}We only want to ship the maps that apply to the current platform; we'd like the others to tree-shake out.
