Is this a good way to solve the quiz "Chessboard" from http://eloquentjavascript.net/02_program_structure.html ?

You find the Question on the bottom of the page.

size = 15; 
grid = ""
for (var i = 1; i <= size; i++) {
 for (var j = 1; j <= size; j++) {
 if (i % 2 === 0) {
 grid+= "# "
 } else {
 grid+= " #"
 }
 }
 grid+= "\n"
}
console.log(grid)

Write a program that creates a string that represents an ×ばつ8 grid, using newline characters to separate lines. At each position of the grid there is either a space or a "#" character. The characters should form a chess board.

When you have a program that generates this pattern, define a variable size = 8 and change the program so that it works for any size, outputting a grid of the given width and height.

This is my code:

 size = 10; 
 
 grid = ""
 
 for (var i = 1; i <= size; i++) {
 for (var j = 1; j <= size; j++) {
 if (i % 2 === 0) {
 grid+= "# "
 } else {
 grid+= " #"
 }
 }
 grid+= "\n"
 }
 
 
 console.log(grid)
