What you are trying to accomplish is rather simple. All you need is a for<\/code> loop that:<\/p>\n

    \n
  1. iterates as many times as designated,<\/li>\n
  2. uses String.prototype.repeat<\/code><\/a> to create as many asterisks as the row number &<\/li>\n
  3. adds the newline character \"\\n\"<\/code> at the end of the string.<\/li>\n<\/ol>\n

    Example:<\/strong><\/p>\n<\/p>\n

    \n
    \n
    \/* The function that creates the desired output for as many rows as given. *\/\r\nfunction createOutput(rows) {\r\n  \/* Create an empty string. *\/\r\n  var str = \"\";\r\n  \r\n  \/* Loop [rows] times and add [i] asterisks & a newline to the string each loop. *\/\r\n  for (var i = 1; i <= rows; str += \"*\".repeat(i) + \"\\n\", i++);\r\n  \r\n  \/* Return the string. *\/\r\n  return str;\r\n}\r\n\r\n\/* Create an output of 5 rows and log it in the console. *\/\r\nconsole.log(createOutput(5));<\/code><\/pre>\n<\/div>\n<\/div>\n

      Since String.prototype.repeat<\/code><\/a> was added in EcmaScript 6, it may not work for everyone. If you encounter that problem, you can supplant \"*\".repeat(i)<\/code> with Array(i+1).join(\"*\")<\/code>.<\/p>\n<\/li>\n
