PICTURE THIS: A SENTENCE BECOMES TOKENS

The model does not read letters like humans. It reads these pieces, then predicts the next one.

Simple meaning

HttpOnly stops document.cookie from reading the session, which reduces XSS token theft.

WHY — Security instead of guessing?

Why interviewers care about Security:

This is a process

question about Security.

Panels listen for order,

trade-offs, and what you would actually do on a Frontend project - not buzzwords.

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 with tokens?

Before the model can read a sentence, it goes through these steps:

1
HttpOnly stops document.cookie from
reading the session, which reduces XSS token theft.
2
SameSite Lax or Strict
stops most cross-site POSTs from including the cookie, which reduces CSRF.
3
Secure plus HTTPS completes
the set I mention.
4
Context mix
Attention looks at nearby tokens together.
5
Next token
The model scores what should come next.
6
Decode
IDs turn back into readable text.

Key takeaway

HttpOnly stops document.cookie from reading the session, which reduces XSS token theft. SameSite Lax or Strict stops most cross-site POSTs from including the cookie, which reduces CSRF.
