Which programming languages have true longevity? That’s not just an academic question; if you’re a working tech professional, you want to know which languages have a good chance of remaining important to the industry over the next decade—or longer.
For data inputs, RedMonk relies on GitHub pull requests and Stack Overflow discussion. “These rankings attempt to correlate trends between language usage and discussion around a language,” reads the firm’s note about its analysis. “We don’t proclaim our rankings to be precise, statistically-valid measurements of popularity; instead we see them as an attempt to aggregate trends across two major communities.” (RedMonk is also refreshingly up-front about changes in its methodology over the years, which it takes into account.)
