Hello, How are you?

createBufferAndSetupAttribute(positionLoc, [
-1, -1,
1, -1,
-1, 1,
-1, 1,
1, -1,
1, 1,
]);

For those position, I hope you explain the position usage.

Thank you.

Please review the first lesson: https://webgl2fundamentals.org/webgl/lessons/webgl-fundamentals.html

// three 2d points
var positions = [
0, 0,
0, 0.5,
0.7, 0,
];

So the positions you given will draw two triangles, they fill the entire canvas.
