 * I’m trying to change some php code within my template to fit it to my needs better,
   and I have 1 small question:
 * What’s the difference between:
    `<?php if (is_single() get_sidebar()); ?>`
 * and:
    `<?php if (!is_single() get_sidebar()); ?>`
 * What does the ! do in front of is_single?
 * Thanks….

 * Reverses the logic.
 * `if (is_single()` = if this is a single post
    `if (!is_single()` = if this is**
   not** a single post
