Three.js - Trying to understand the vertices array data within a js file

Question

I am trying to understand the vertices array data within a js file. Does anyone know what all those numbers inside the vertices array are? Are they the position (x,y,z) of each vertex? Here is an example of a js file.

[x1, y1, z1, x2, y2, z2,....,xn, yn, zn]
