Explaining Javascript is not Java

Question

What is a good strategy for explaining to a person who does not know the difference between Javascript and Java?

For newbies, I don't want to over-explain and confuse them.
For both newbies and others starting to learn coding, I don't want to just say "it isn't the same thing" as some may ask more questions I'm not prepared for.

EDIT: Do I mention about NodeJS, etc. or do I leave that until they would ask (or are more knowledgeable about Javascript?)
EDIT 2: I'll wait for some answers before picking.

Answer 1

The simplest answer is JavaScript is for your web browser and Java is a cross-platform language.

I would save NodeJS for someone who has worked with JS. However, I would mention that JS can be used in back and front end development.

Answer 2

java is to JavaScript like car to carpet. ;)
