Answer 1

No, but you do need to be good at logical thinking.

People speak of right and left brain dominance, but I find much of that to be fiction. After all, art is dominated by lines of symmetry and projection, and music is mathematical harmonization. Javascript and programming is much the same.

Great programming is much like composing a great piece of music or art. The picture/piece as a whole needs to make sense. Math, where used, is just a means to an end.

I rarely need to use higher level math than basic arithmetic and knowledge of Arithmetic operators in Javascript. Sure, sine functions are useful for graphical transitions, but those are mostly abstracted away.

What I do rely upon is making sure I'm well organized (sloppy Javascript is really an easy hole to fall into), and trying to simplify the number of third party libraries / dependencies I am using.

It's about creation.

Writing great programming is as euphoric as creating any work of art, and ultimately much the same process.

I would strongly encourage you to explore it. Start simple. Learn the basics. Do not be afraid of the syntax or indeed the math.

Answer 2

Do you know how to solve a linear equation ?
If yes then you can start learning JavaScript, otherwise learn math.
It really depends what you mean by poor skills.

Answer 3

No, not unless you plan on doing math calculations in your script. Otherwise, the only "basic mathematics" you should understand in regards to JavaScript is "order of operations".

Answer 4

no. but you ll need it if the code uses math concepts
