Geometric Pattern with "Nested for loops" in p5.js

Nested for loop is a for loop inside a for loop .It can be used in different ways.I have used here to make geometric pattern in combination with dist(), translate(), rotate(),push and pop() functions. https://editor.p5js.org/ri1/sketches/ROUKawjoW
