Why you use const keyword? Can you please tell me?

That <a href="https://medium.com/javascript-scene/javascript-es6-var-let-or-const-ba58b8dcde75#.f2e4084ua">article</a> fits with my point of view. In short: I use `const` if a variable won't be reassigned. `let` is a signal that the variable will be reassigned (loops and etc)

Good submission. But wrong: <pre class='brush: javascript'>const sorted = array.sort((a, b) => a - b); </pre> Use for copy: <pre class='brush: javascript'>const sorted = array.slice().sort((a, b) => a - b); </pre>
