Where is the best place to look for JavaScript programmers for a project?

Question

JavaScript

I am currently working on a project that requires a chief programmer. Basically working on a browser extension.
Everything is in JS, I was also recommended to look for a person working with React and Redux.
I searched for freelance, I also searched for similar services on freelance. I could not find suitable people for the role of lead programmer.
Can you tell me where such programmers hang out? Some groups, communities. And the project just needs a good programmer, nothing super cool.

Answer 1

Basically working on a browser extension.

I was also recommended to look for a person working with React and Redux.

Ask to look for the one who recommended it to you.
