6. switch 简化 我们可以将条件保存在键值对象中,并根据条件来调用它们。 7. 条件查找简化 如果我们要基于不同的类型调用不同的方法,可以使用多个 else if 语句或 switch,但有没有比这更好的简化技巧呢? // Longhandif(type==='test1'){test1();}elseif(type==='test2'){test2();}elseif(type==='...

If there are two items in the Stars array and three in the Cast array, all five items’ content will be rendered. This is a good situation to use the #data keyword, too, if the items in the arrays aren’t objects (with properties) but simple string values. For example...
Its nodes are values of class DataFlow::Node, which has two subclasses ValueNode and SsaDefinitionNode. Nodes of the former kind wrap an expression or a statement that is considered to produce a value (specifically, a function or class declaration statement, or a TypeScript namespace or enum...
