JavaScript
var age = 26;
var beverage = (age >= 21) ? "Beer" : "Juice";
console.log(beverage); // "Beer"
(condition) ? (if true, do this) : (otherwise, do this)//ternary operator example:
var isOpen = true; //try changing isOpen to false
var welcomeMessage  = isOpen ? "We are open, come on in." : "Sorry, we are closed.";

condition ? expression-if-true : expression-if-false;

function findGreater(a, b) {
  return a > b ? "a is greater" : "b is greater";
} if ($scope.SearchSalesOrderAndCompanyName !== undefined && $scope.SearchSalesOrderAndCompanyName != null ) {
            SearchCriteria += " AND [SalesOrderNo] LIKE '%" + $scope.SearchSalesOrderAndCompanyName + "%' OR ([SO].[CompanyNameOnBill] LIKE '%" + $scope.SearchSalesOrderAndCompanyName + "%')";
        }
        if ($scope.FromDate !== undefined && $scope.FromDate !=null) {
            SearchCriteria += " AND [SO].[SalesOrderDate] LIKE '%" + $scope.FromDate + "%'";
        }
      isMember ? '$2.00' : '$10.00'
// isMember true =>  output: "$2.00"

// isMember false =>  output: "$10.00"

// isMember null =>  output: "$10.00"
