Those should be included for certain. There’s no reason to use “array of xxx” syntax if can’t use push etc… I don’t even use them in FPC because they lack  simple array features that every other language has. Dynamic arrays really should be a "toll-free bridge” to JSArray but with types for safety. Otherwise just use JSArray always.

Thanks. The trunk version appears to be a subclass of an array which is probably the way to go. I built from pas2js from the SVN sources but I got a syntax error. Is that not the trunk version?

You could just add a constructor in there then couldn’t you?

type
 TJSFloat32Point = class external name 'Float32Array' (TJSFloat32Array)
 public
   x: Float32; external name '[0]';
   y: Float32; external name '[1]’;
 end;
