常见的想当然

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

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• 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})');
