+/** If you have lines that are just instructions or notes for humans and you don’t want the computer to execute them, you can turn them into comments.
+
+In JavaScript, there are two ways to write comments:
+
+1. Single-line comment
+
+Use // at the start of a line.
+Everything after // is ignored by the computer.
+
+Example:
+
+// This line explains what the code does
+const num = 8;
+
+2. Multi-line comment
+
+Use \ /* ... *\ / to wrap several lines.
+
+Example:
+This section is just instructions
+The computer will ignore everything between these symbols
+
+const num = 5;
