what happens if you delete your recycle bin code example

Example 1: How do I see which version of Swift I'm using

// Open the Terminal and write:

swift -version

Example 2: How do I check if an element is hidden in jQuery?

// Checks CSS content for display:[none|block], ignores visibility:[true|false]
$(element).is(":visible");

// The same works with hidden
$(element).is(":hidden");
