Ecma International, which oversees the ECMAScript standard for JavaScript, has introduced an alternative license for JavaScript that is intended to be more permissive regarding derivative works, Mozilla said this week.
With the move, Ecma now provides two licenses, either of which can be adopted depending on the needs of a given technical committee, Mozilla said. Whereas ECMAScript is licensed by Ecma, other web technologies such as CSS and HTML are licensed more permissively by the World Wide Web Consortium (W3C). The different licenses create overhead for legal review, Mozilla said, which can impact contributions.
