Hi, you can definitely do the math with the standard JavaScript Math.* API. Also there is a modified glMatrix framework, already included in Blend4Web (accessed by "vec3", "mat4" etc.) And finally there is some useful API in our "util" module.

About the logic bricks. We think that their functionality is too limited and it's not possible to do any non-trivial stuff using them. This means that eventually you still need to know python and some bpy API. Our language is JavaScript so there is some incompatibility arises . But we did some work in NLA scripting so follow our future releases.

I would like to create a "chasing lights" effect using Blend4Web

Hi! Do you have some reference video/screenshot?
