.CLS File

The cls file extension is related to JavaScript, a scripting language most often used for client-side web development. It was the originating dialect of the ECMAScript standard.

It is a dynamic, weakly typed, prototype-based language with first-class functions. JavaScript was influenced by many languages and was designed to look like Java, but be easier for non-programmers to work with.

The cls file contains JavaScript class definitions.
