維基百科中關(guān)于DOM的介紹這樣寫到：The Document Object Model (DOM) is a cross-platform and language-independent application programming interface that treats an HTML, XHTML, or XML document as a tree structure wherein each node is an object representing a part of the document. The objects can be manipulated programmatically and any visible changes occurring as a result may then be reflected in the display of the document.[2]其中的"language-independent"該怎么理解，為什么說dom是"language-independent"的？
