To Use or Not to Use: Are HTML Script Tag Attributes \'Type\' and \'Language\' Still Necessary?

The Debate: HTML Script Tag Attributes - Type or Language, or Omit Both

For years, web developers have debated the appropriate attributes to include within the HTML script tag. Traditionally, options have included the "type" and "language" attributes. However, the W3C has introduced new standards, raising questions about the continued relevance of these attributes.

Deprecation of "language" Attribute

The "language" attribute has officially been deprecated, rendering it obsolete for use. During the development of HTML5, it was discovered that all browsers uniformly treated "text/javascript" as the default script type. Consequently, the W3C has standardized "text/javascript" as the default value, making the "language" attribute redundant.

Omission of "type" Attribute

Even the "type" attribute has become optional. W3C standards now allow for the omission of both the "type" and "language" attributes. This decision was based on the widespread use of "text/javascript" as the default script type across browsers.

Exceptions for XHTML and HTML 4.01

For pages written in XHTML 1.0 or HTML 4.01, omitting the "type" attribute is not recommended, as it may result in validation errors.

Recommendation

In accordance with current W3C standards, the omission of both the "type" and "language" attributes is generally preferred. This approach ensures compatibility with modern browsers and aligns with the recommended best practices.
