How can I exit from a javascript function?

javascript, jquery

Solution

if ( condition ) {
    return;
}

The `return` exits the function returning `undefined`.

The `exit` statement doesn't exist in javascript.

The `break` statement allows you to exit a loop, not a function. For example:

var i = 0;
while ( i < 10 ) {
    i++;
    if ( i === 5 ) {
        break;
    }
}

This also works with the `for` and the `switch` loops.

Problem

I have the following: ``` function refreshGrid(entity) { var store = window.localStorage; var partitionKey; ... ... ``` I would like to exit from this function if an "if" condition is met. How can I exit? Can I just say break, exit or return?
