Okay, let's see what “the standard” has to say…
“Clauses 18 through 28 define the ECMAScript standard library.”
—ECMA-262, 12th edition, June 2021, ECMAScript® 2021 Language Specification, §4.5
“Clauses 18 through 28 define the ECMAScript standard library.”
—ECMA-262, 12th edition, June 2021, ECMAScript® 2021 Language Specification, §4.5
(Does the standard provide for a way not to run with the "standard library"? To opt for a different library of your choosing, for example, or no library at all? No? So it's a set of built-ins that are just an inescapable part of the language, then.)
