Let me tell you the rules of the game first: Find a block of a different color and click on it among the changing number of color blocks. Let me share with you how to implement the game of finding different color blocks through js code. Friends who need it can refer to it

Game rules: Find a block of different colors among the changing number of color blocks and click

The constructor in JS is used here to create elements
