Hi Juan,
JavaScript:
// In the Script Editor, edit a .js file containing this text,
// position the cursor immediately prior to the 1,
// then type two backslash characters, i.e., //, in an attempt to comment out the 1 *
// note that backslashes are incorrectly inserted after the *.
function a() {
this.b = function() {
return (
1 *
2
);
};
}
