1.VB.NET

Visual Basic.NET, a language created by Microsoft, has syntax similar to BASIC and a coding style similar to C#. As developers actively adopt modern languages such as .NET and C#, it may soon end up on the shelf.

2. Elm

It was developed as a domain-specific language for declaratively creating web-browser-based graphical user interfaces. It's considered a dying language, since it has been inactive for the last two years, with no substantial updates.

3. Coffee Script

Although it's known for its prettier appearance and efficient destructuring, it's notorious for the ambiguity it adds to programming. Coffee Script doesn't have an explicit scope definition feature or real functions, which is the main reason for its decline in the popularity charts.

4. Haskell

The culmination of not-very-popular languages such as Miranda and Clean, it was used by firms and projects such as Facebook and Github. Lately, it's been dropping in RedMonk's rankings, despite major updates in recent years.

5. Erlang

A general-purpose language adopted mainly by telecommunications systems, it hasn't done so well in the job market. Although it was consistently present last year, its community involvement wasn't as good.

6. Pascal

A direct descendant of Algol 60, it once ruled as an imperative and procedural programming language. Now that Delphi has taken over that role, the PASCAL language has been pushed into the background.

7. Cobol60

COBOL was mainly created for business applications, and it was bound to give way to Java's more convenient static typing or Python's dynamic typing. Because of its strict typing rules and the complexity of parsing, companies are choosing other languages.

8. Cold Fusion

It was launched by Adobe with several advanced features for developing web and mobile applications. In addition, it comes in different versions that developers and businesses can use according to their needs. But because of its poor debugging and lack of a package manager, it's gradually losing popularity.

9. Objective-C

Once a popular language for developing Apple applications, it's being quickly replaced by Swift. More and more developers are choosing Swift over Objective-C because Swift is feature-rich. Still, it hasn't fallen as low as you might expect, thanks to legacy code.

10. Perl

This is a collective name given to a group of high-level, general-purpose, interpreted, and dynamic programming languages. Although its main drawback is its heavy CPU resource consumption, it's becoming redundant as programmers turn to other modern languages.
