さすが: living up to expectations
Praise or react when someone/something matches a strong prior expectation.
In short
さすが often means “as expected of…” or “that is impressive, just as you would expect.” It can stand alone as a reaction or modify a noun phrase with さすが（は）.
How it works
Unlike neutral やっぱり, さすが commonly carries admiration or acknowledgement of reputation/ability.
Useful contrast
Tone matters: it can be warm praise, playful, or occasionally ironic.
Examples
さすがですね。
Impressive, as expected.
さすが先生です。
That is what you would expect from a teacher.
Common pitfall
Do not use it for every “as expected”. Use it when the expectation is tied to someone’s quality, status or known ability.
