Question

here’s one something i ran into today.

ok

[].push(
  function() {return 1;},
);

not ok

[].push(
  function() {return 1;},
  function() {return 1;},
);

anyone know what’s going on here?

thanks!

Answer 1

Both work fine as long as there is no trailing comma after the last argument:

[].push(
  function() {return 1;},
  function() {return 1;}
);
