Simple meaning

Inside a form, the default type is submit, so a random button can post the form by accident.

WHY — HTML instead of guessing?

Why interviewers care about HTML:

They want a clean

contrast on HTML, not two memorised paragraphs.

Say what changes for

the developer, then one case where picking wrong hurts.

Stay structured

Name the idea, why it exists, then one short example.

Close cleanly

End with when you use it and one common pitfall.

STEPS — What happens step by step?

Before you speak the answer, walk the interviewer through these steps:

1
Inside a form, the
default type is submit, so a random button can post the form by accident.
2
Type button does nothing
until JavaScript handles the click.
3
I always set type
explicitly in React forms for that reason.
4
Give an example
One tiny concrete case you can say aloud.
5
Common mistake
What juniors usually get wrong.
6
Close
When you pick this over the alternative.

EXAMPLE — See it in action

Here's a short line you can speak, broken into clear beats:

Say this line

“Type button does nothing until JavaScript handles the click.”

Key takeaway

Inside a form, the default type is submit, so a random button can post the form by accident. Type button does nothing until JavaScript handles the click.
