在Scala中,把哈希表这种数据结构叫做映射 1. 构建映射 2. 获取和修改映射中的值 好用的getOrElse 注意:在Scala中,有两种Map,一个是immutable包下的Map,该Map中的内容不可变;另一个是mutable包下的Map,该Map中的内容可变 例子: 注意:通常我们在创建一个集合是会用val这个... ...

These concerns reflect design flaws in JavaScript not NArr. Size Inconsistency and Mutability Concerns. Every scala.Array has an immutable length while any js.Array can grow or shrink dynamically. To mitigate the usual dangers of shared mutable state, users of NArr had better treat all instances ...
Mutable vs Immutable Data Types Shallow Copy Only Community Input Array.from is Another Way to Clone Array Resources # Why Can’t I Use = to Copy an Array?Because arrays in JS are reference values, so when you try to copy it using the = it will only copy the reference to the original...

The "done" property should be set to true only if there is no "value" in the result. Note that "done" only reflects whether the iterator is done at the time "next" is called. Future calls to "next" may or may not return more rows for a mutable data source. In order for JET ...
