Funny you mention nobody uses var anymore when I just saw a post on here yesterday that perf critical code still uses var since it's faster

Bundlers will convert let/const to var, assign classes and functions to var etc but generally people don't write it themselves unless they want to (ab)use its semantics for performance reasons.

Do people often use bundlers for the backend?
