Python and Java rank first and second in both employer demand and popularity with developers. It’s interesting to note that supply and demand for these key languages are aligned.
The gaps in volume between languages are significant, effectively dividing the list into four tiers:
The first tier consists of the top five languages (Java, Python, SQL, C++, and Java Script), which have enough volume to stand in a league of their own.
The second tier (Bash and C#) sees a significant drop in volume, with Bash having only 25% of the volume of JavaScript.
The third tier (Go, TypeScript, R, and PHP) have similar demand levels and are growing the fastest.
Rounding out the list is the fourth tier (C, Swift, and Ruby), whose languages barely post enough volume to rank on the list.
