What is comment

Answer 1

/* In real life, you know what's a comment unless you're a robot */
/* In coding, a comment is something you think and express about any part of a code. You may want to express it explicitly in the code, but you are afraid that it may cause exceptions. So you put it in between /* */ or in the same line after //. This makes sure it doesn't get compiled. */
<!-- Comments are important as they can be used to describe parts of a code. It's a good practice to do this. -->
