Strings

String.prototype.*

None of the string methods modify this – they always return fresh strings.

• charAt(pos: number): string ^ES1

  Returns the character at index pos, as a string (JavaScript does not have a datatype for characters). str[i] is equivalent to str.charAt(i) and more concise (caveat: may not work on old engines).

Code Splitting

NOTE: This gist uses the master branch of ClojureScript. Clone ClojureScript and from the checkout run ./script/bootstrap and ./script/uberjar. This will produce target/cljs.jar which you can use to follow this guide.

As client applications become larger it becomes desirable to load only the code actually required to run a particular logical screen. Previously ClojureScript :modules compiler option permitted such code splitting, but this feature only worked under :advanced compilation and users would still have to manage loading these splits. :modules also required manual
