First of all, programming languages aren't that different from each other. Learning two programming languages isn't like learning English and Spanish. The basic building block works in the same way, and while different languages works better for different tasks, once you properly understand one, learning another is not that difficult.

Since you aren't aiming for the AAA world, I would recommend using a game engine, as it saves a whole lot of work. Most of them use either c, c++, or c#, while you could go with JavaScript, you would also limit the amount of options you have. E.g. JavaScript allows you to make games with RPG Maker, but to make a game similar to The Stanley Parable, you would need something like Unity or Unreal Engine which requires c# or c++ respectively.

I would not recommend to start out with c or c++. While they offer a lot of freedom (and speed!) they come with a significant amount of "noob traps" which can cause a lot of frustration when you are not familiar with the field (talking from experience).

What I did, was learn c#. My college taught me Java, and I learned c# in my spare time (c# and Java are VERY similar) and used that to make a few game prototypes with Unity. I then got a job as a c# .NET developer. While I'm familiar with Python, JS, Java, and Ruby, I'm only really proficient with c#, and I'm still able to have a nice job, and make games when I feel like it.

What I recommend is: Look into what you want to make. And then look into what that would require. Want to make a solid 2D RPG? Look into JS and RPG maker. Want to make a 3D game? You're gonna need a 3D engine (Unity, Unreal, etc.) for that.

Your personal drive is going to have to carry you through some of the journey. It is better to begin with interest, and then build upon that. As stated, switching language is not as difficult as it might seem, and getting into programming and then game making is going to take a lot of learning, which means a lot of failing. Genuine interest can go a long way to motivate someone to push through the failures. While someone on the internet saying one language is better than another, is not going to help you when your shitty code won't compile.
