I have this code:
<!--
Added worldGen and biomeGen and treesGen variables at the start
Noise seed changing
Added sand texture and block
Added biomes property to each type of block in the "blocks" variable
Added getBiome function
Added a biome variable inside the world generation codes - determines the biome based on the biomeGen
Added "&& blocks[b].biomes.includes(biome)" in if statement for creating the new block object
Added oaklogindex and oakleavesindex variables
Added making trees code - added treeNoise variable inside world generation codes
Added code for logs (tree trunks)
Added treeDetecting algorithm for leaves
Added code for leaves
-->

I tried this code, but the game keeps runing at 16 fps. I dont knowhow to appilate the cubes forming a big mesh, but in another games like minecraft its more optimized than the original, keeps rendering at 16 chunks with a processor of 1th generation, in minecraft with a 4th processor renders fast at 11 chunks. Any solution? Thanks anyway!
