Developers beware: Learning just one programming language could severely limit your career options, according to a new report from Coding Dojo. None of the top 25 companies in the Fortune 500 use just one coding language for their products and services—on average, they rely on four different languages, the report found.
Software development is a constantly shifting field, and many languages live and die within a few years. Developers must continually pick up and sharpen new skills to remain relevant in the job force.
"Much like any tool or application, companies use different coding languages for different requirements; there's not a one-size-fits-all option," Speros Misirlakis, Coding Dojo's head of curriculum, said in a press release. "While specific jobs might focus on a particular language, this research shows that a single language could be a long term dead-end. Aspiring and existing developers must learn coding's common building blocks and ultimately become fluent in multiple languages to have the adaptability and flexibility for a successful career."
In the report, Coding Dojo analyzed the coding requirements for all software development job listings among the top 25 Fortune 500 companies on job search site Indeed. JavaScript was the most-listed coding language in these job openings, followed by Java, Python, Ruby, and Perl.
Java is likely the most popular language overall, as all Android apps are based on it, and 90% of Fortune 500 companies use it, according to a report from IDC. Java was also recently found to be the most in-demand tech skill for employers, appearing in 30% of all Indeed tech job postings from August to December 2017.
