WebGLSL has very flexible notation for referring to the components of a vector. One way to access them is with array notation. For example, if v is a four-component vector, then its components can be accessed as v [0], v [1], v [2], and v [3]. But they can also be accessed using the dot notation as v.x, v.y, v.z, and v.w.
