There are three ways to add elements to a JavaScript array.<\/p>\n

    \n
  1. With the push() method, you can add one or more elements to the end of an array and it will return the new length of the array. For example:<\/li>\n<\/ol>\n
    var arr = [1, 2, 3];\r\narr.push(4); \/\/ [1, 2, 3, 4]\r\n<\/code><\/pre>\n
      \n
    1. By using the unshift() method, you can add one or more elements to the beginning of an array and it will return the new length of the array. For example:<\/li>\n<\/ol>\n
      var arr = [2, 3, 4];\r\narr.unshift(1); \/\/ [1, 2, 3, 4]\r\n<\/code><\/pre>\n
        \n
      1. The concat() method is used to merge two or more arrays and return a new array. You can use the concat() method to merge the elements to be added into a new array, and then replace the original array with the new array. For example:<\/li>\n<\/ol>\n
        var arr = [1, 2];\r\nvar newArr = arr.concat(3); \/\/ [1, 2, 3]\r\n<\/code><\/pre>\n","protected":false},"excerpt":{"rendered":"
