为了编写可维护的代码,我们把很多函数分组,分别放到不同的文件里,这样,每个文件包含的代码就相对较少,很多编程语言都采用这种组织代码的方式。在Node环境中,一个.js文件就称之为一个模块(module)。 使用模块有什么好处? 最大的好处是大大提高了代码的可维护性。其次,编写代码不必从零开始。当一个模块编写完毕,就...

Motivation Similar to #2270, I forgot to require the space for modules too. Implementation Switched the regex to \s+ instead of \s*.
The @page rule becomes even more powerful when paired with pseudo-class page selectors. Styles can apply to discrete pages, such as left page, right page, first page, or title page.Page Margin Boxes Page RegionsContent can be replicated across pages within specifc page margin boxes. They ...

Of the two languages, Ruby seems to be better suited to a pure class-oriented approach, as it comes with a built-in class system that is intended to accommodate additional subclassing. Nonetheless, both languages give programmers the flexibility to either permit or circumvent a purely class-...
