Oh, really!? I'll be very glad NOT to work at a company that throws aways candidates because of such triviliaties.
It is never advice toward hiring manager. It was always criticized as not smart and leading to many false rejects.
I write it as nodejs because that's how I got used to it on the mailing lists and several places that I frequent.
If a "team" decides not to hire me because of the latter, then ... thanks, I guess?
But at this point we're getting into the territory of what's seen as a positive in some niche communities may not be seen as a positive signal outside that community. And in business communications, what masters most is knowing who your audience is, and how your message is received.
It’s ego.
What is the résumé’s job? To convey experience and work in a positive light. A small typo that may incidentally be the correct spelling shouldn’t derail that if the goal is to hire the most talented people.
To my defense, I was going by my Bayesian prior for certain language names for which one could be 100 percent sure there was no alternate accepted spelling or capitalization.
So if one put JAVA or PERL on their resume, that would generate a definite "pass" signal.
Or even if it's just 1 or 2. It's infinitely better to hire someone who is in fact really solid at what they say they know, than someone who tries to spam you with every random keyword they've been exposed to in the hope that you won't drill down and ask them any hard questions about most of them.
That, and skill listings that don't pass the "apples and orange" test. For example:
Programming languages: Java, Perl, PHP, XML, HTML, CSS, Bootstrap
Know yourself, and know your audience.
In some software, say, nuclear warhead tracking software, you want those people.
