Yes you can. As per Zac's suggestion it looks like you're missing some
vital pieces here. For one, you should give each loaded script a name. If
an error occurs it'll give you the name of the script the error occurred in
along with the line number of THAT script. Also, you should run the script
after each compile. I'd also add a TryCatch in case something went wrong.
Otherwise if this isn't what you need you could also concatenate the script
in your program elsewhere and load it once. If you are using multiple
contexts within the same isolate just be sure you have the correct context
scope for the one you're loading.
(This will be my first time writing a code block in this forum so hopefully
it comes out right).
//Assume you did all the necessary setup like isolate scope, handle scope,
context scope, locker already...
Local<String> nameOfScript = String::NewFromUtf8(isolate, "a.js");
Local<String> sourceOfScript = String::NewFromUtf8(isolate, "<code of a.js>"
);
ScriptOrigin origin(nameOfScript); //<- for the name of script being
compiled
Local<Script> script = Script::Compile(sourceOfScript, &origin);
Handle<Value> result = script->Run();
//Now do the same as above for script b.js
//NOTE: I'd add a TryCatch in here too in case something went wrong in the
compile/load/run of each script.
