These two encodings typically look exactly the same when displayed by a text editor, but they have different binary encodings, meaning that they are considered different by JavaScript, which can lead to very confusing programs:如果在 JavaScript 程序中使用非 ASCII 字符,则必须知道 Unicode 允许对同一...
模块 §10.3 文档了 JavaScript 模块,并涵盖它们的import和export指令。如果您使用模块编写了 JavaScript 程序(并且没有使用代码捆绑工具将所有模块组合成单个非模块化的 JavaScript 文件),那么您必须使用带有type="module"属性的标签加载程序的顶层模块。如果这样做,那么您指定的模块将被加载,它导入的所有模块也将被加载...

The example in this section demonstrates importing methods which have a JS Date object as its return or parameter. Dates are marshalled across interop by-value, meaning they are copied in much the same way as JS primitives.A Date object is timezone agnostic. A .NET DateTime is adjusted ...
export default SpecificErrorRequest 这里要记住的一件事,清除异常通常会有不同的触发器。 使用'x'删除异常是没有意义的。在这里,在发出新请求时清除异常会更有意义。你还可以在用户进行更改时清除异常,例如,当输入值改变时。 前端的异常 如前所述,这些异常可以与来自后端的特定异常以相同的方式(状态)处理。 我...
A username is no longer just a string, it’s a specific kind of value that has a semantic meaning. With opaque types it becomes trivial to find every use of Username in your program, which makes both refactoring and debugging much safer and easier. To take a fairly common class of bug...

The parent table that this property references may also be nested, meaning it would refer to a different parent table. The top-level table can always be referenced via the tableController property. If only one nested table exists, then the values of tableController and tableParent are the same...
The flags mean that // existing files won't be overwritten, and that if the filesystem supports // it, the copy will be a copy-on-write clone of the original file, meaning // that no additional storage space will be required until either the original // or the copy is modified. fs...
Enforce a rule that tests must be written in "async" style, meaning each test provides a done callback or returns a Promise. Non-compliant tests will be marked as failures. # --bail, -b Causes Mocha to stop running tests after the first test failure it encounters. Corresponding "after ...
