What's the difference between using link and script tag to reference JavaScript source?
link
tag is used to relate stylesheets or any other linked documents instead of including javascript files.
The HTML Link Element <link>
specifies relationships between the current document and other documents. Possible uses for this element include defining a relational framework for navigation and linking the document to a style sheet.
rel
Attribute:
This attribute names a relationship of the linked document to the current document. The attribute must be a space-separated list of the link types values. The most common use of this attribute is to specify a link to an external style sheet: the rel attribute is set to stylesheet, and the href attribute is set to the URL of an external style sheet to format the page. WebTV also supports the use of the value next for rel to preload the next page in a document series.
Possible Values:
alternate - An alternate version of the document (i.e. print page, translated or mirror)
stylesheet - An external style sheet for the document
start - The first document in a selection
next - The next document in a selection
prev - The previous document in a selection
contents - A table of contents for the document
index - An index for the document
glossary - A glossary (explanation) of words used in the document
copyright - A document containing copyright information
chapter - A chapter of the document
section - A section of the document
subsection - A subsection of the document
appendix An appendix for the document
help A help document
bookmark A related document
shortcut icon A related (favorite icon) image of the document
While The HTML Script Element <script>
is used to embed or reference an executable script within an HTML or XHTML document.
The second (using link
) shouldn't work or run and is non-standard.
