O que costuma-se supor

a regular expression with named capture groups compiled by Babel will preserve the exact syntactic shape of the pattern in its .source property

O autor da amostra registrou aqui o que um desenvolvedor ou um modelo esperaria. O contrato abaixo é o que de fato rodou.

Contrato

• the .source property of a named capture group regex transpiled for IE11 evaluates to a string stripped of the capture group names, rather than the original source string
• assert.strictEqual(nativeRegex.source, '(?<year>\\d{4})-(?<month>\\d{2})-(?<day>\\d{2})');
• assert.strictEqual(transpiledRegex.source, '(\\d{4})-(\\d{2})-(\\d{2})');
