I've seen function with a + symbol at the beginning like this
+(
function () {
console.log("Hello World");
}
)
();
What does + means?

it turns the proceeding expression into a Number. for the example shown, it's silly because `;` would work – dandavis Jan 11 '17 at 18:42

The `+` doesn't serve any purpose here. – Felix Kling Jan 11 '17 at 18:47
