Javascript Incompatibilities/Inconsistencies [closed]

Answer 1

Well, there's a problem with implied semicolons.

return {
    a: 1,
    b: 2
}

Some people like opening brackets on its own line, like this:

return
{
    a: 1,
    b: 2
}

However, this last statement will return undefined, since the parser sees:

return;
{
    a: 1,
    b: 2
}
