One of the easiest I found is Heaps algorithm: It generates each permutation from the previous one by choosing a pair of elements to interchange. this many characters to the string to be logged. There are a lot of the algorithms that generate permutations. times, and log a row to console each time, and the second loop will add sets size of board, since the first loop will run for this amount of

I'm sorry this is a bit wordy, hope it makes sense.I'll put some comments in the actual code below.
This is how the second for loop accomplishes the same thing as your string1 and string2. So in the first row i is always 0, and j will be 0, then 1, then 2, etc.so total be divisible by 2, then not divisible by 2, then divisible by 2, etc.then in the second row i will be equal to 1, and j again will be 0, then 1, then 2, etc.so now total will first not de divisible by 2, then divisible by 2, then not, etc.for the third row, i will be 2, which will basically act as i being 0 since both 0 and 2 leave no remainder when divided by 2. If the index of the row is odd, don’t apply the flex-direction. This direction of render can be determined by the CSS property flex-direction. I finally got something together after scratching my head for a very long while. I did codecademy already and am working through Eloquent Javascript now. Use chessboard.js to have a tactics website where users have to guess the best move. The rule is if total is divisible by 2, then add a "#", and if not, then add a " ". One way would be to alternate the direction in which the rendering takes place. Question: How do I solve the Eloquent Javascript 'Chess Board' tsaiDavid tsaiDavid asked at at 21:42 at 21:58. Use chessboard.js to show game positions alongside your expert commentary. Instead of having to declare two strings like you did in the first version, it knows how each row should end up looking based on some variables and a rule. Fizzbuzz, creating triangles, and creating a chessboard. The second for loop will actually build the line, or row, adding to var line for each column in the row. My solutions to the three example problems in Chapter 2 of Eloquent JavaScript, by Marijn Haverbeke. One of the end of chapter exercises has the reader create an 88 chess board with rows that follow this pattern. It will log to console for every line, or row, if you prefer. JS Creating a chess board from Eloquent JavaScript I recently started to teach myself JS and stumbled across the eBook eloquent JavaScript. The first for loop declares the var line and eventually logs it to console. chess-board-example/index.

Plain english explanation of second one - the var size = 8 will be the size of the board. An example page showing how to implement nested for loop logic.
