each

• A generic iterator function, which can be used to seamlessly iterate over both objects and arrays. Arrays and array-like objects with a length property (such as a function’s arguments object) are iterated by numeric index, from 0 to length-1. Other objects are iterated via their named properties.

상황에 따라서 루프에서 break 또는 continue 조건을 넣어야할 때 가있다.

루프내에서 return 1 일 경우, continue 의 역할을 한다. 반대로 0일 경우에는 break 역할을 한다.

We can break the $.each() loop at a particular iteration by making the callback function return false. Returning non-false is the same as a continue statement in a for loop; it will skip immediately to the next iteration.

True : This is equivalent of ‘break’ for jQuery loop

False : This is equivalent of ‘continue’ for jQuery loop
