The desire not to get out of one language is laziness?

Question

IT education

In principle, there is no need to go far for an example - after all, I myself am such a person. I started with javascript / typescript a few years ago, and found a job, and now I work with it to this day.
Tried to try c#, and go, and php, but everything ends - wow! Here you can do it like this, and you can do it like this. Great! But I don't want to work with it somehow.
However, within js/ts there is always a huge desire to learn something new or in technologies that are not related to a particular language.

Is this a problem for me as a specialist, and can it negatively affect my future?
Or are all these predispositions to the language - nonsense, and more perseverance in learning is needed? As they say, it is always unpleasant to get out of the comfort zone (A habitual language).

Answer 1

On the one hand, it is normal for the front to know only JS, since there is nothing else on the front, if we discard the nuances. On the other hand, learning new things trains the brain, increases its plasticity, and allows you to look at problems from different angles. All this is useful, both for professional growth and for health.
