DepthTexture: Blank Screen while implementing it

I tried depth texture implementation of the example from threejs.org on my local machine. https://github.com/mrdoob/three.js/blob/400acd3c78c8e631087322eb1e0e9fc00a16b375/examples/webgl_depth_texture.html

However I am not getting the same output screen, rather a blank screen.
jsfiddle link of the implementation : https://jsfiddle.net/MrOrangeSky/L48vj3hx/8/

I can’t find the reason for same.

If you copy code from the examples, you have to make sure to use the same three.js version. By updating your library files from r101.1 to r117.1, the demo works as expected.
