Implode an array with JavaScript

Question

Can I implode an array in jQuery like in PHP

User · Answer

For future reference  if you want to mimic the behaviour of PHP s implode   when no delimiter is specified  literally just join the pieces together   you need to pass an empty string into Javascript s join   otherwise it defaults to using commas as delimiters   var bits     H    e    l    l    o         W    o    r    l    d    alert bits join           H e l l o   W o r l d alert bits join           Hello World

Array join is what you need  but if you like  the friendly people at phpjs org have created implode for you   Then some slightly off topic ranting  As  jon darkstar alreadt pointed out  jQuery is JavaScript and not vice versa  You don t need to know JavaScript to be able to understand how to use jQuery  but it certainly doesn t hurt and once you begin to appreciate reusability or start looking at the bigger picture you absolutely need to learn it

Use join   method creates and returns a new string by concatenating all of the elements in an array   Working example   x000D   x000D  var arr    A   b   C   d  1  2  3  4    x000D  var res  arr join       x000D  console log res   x000D   x000D   x000D

array join was not recognizing     how a separator  but replacing it with comma  Using jQuery  you can use   each to implode an array  Note that output saved json is the array and tmp is the string that will store the imploded array    var tmp         each output saved json  function index value        tmp   tmp   output saved json index              output saved json   tmp substring 0 tmp length - 1      remove last     added   I have used substring to remove last     added at the final without necessity   But if you prefer  you can use instead substring something like   var tmp         each output saved json  function index value        tmp   tmp   output saved json index        if  index   1     output saved json length             tmp   tmp                   output saved json   tmp    I think this last solution is more slower than the 1st one because it needs to check if index is different than the lenght of array every time while   each do not end
