“JavaScript’s continued strength is impressive, as is Java’s
steady, robust performance.
The long time presence of these two languages in particular
atop our rankings is no coincidence; instead it reflects an
increasing willingness to employ a best-tool-for-the-job
approach, even within the most conservative of enterprises.
In many cases, Java and JavaScript are leveraged side-by-side
in the same application, depending on its particular needs.”
