Syntactic differences aside, the capabilities of JavaScript and Python do not differ significantly. They are both highly popular highly dynamic object-oriented-ish languages. Knowing that the most prevalent implementation of one is significantly faster than the most prevalent implementation of the other is useful information for someone deciding between the two for a project where performance is important. Comparing alternative implementations of the languages, which are geared toward performance, would also be valuable. But simply knowing that, if your choice to use CPython is more-or-less arbitrary, you're leaving performance on the table, is valuable. (Of course, as discussed in the top-level thread by @SuchAnonMuchWow, this particular benchmark seems to be comparing apples to oranges, and thus may not be of much value.)
