How to print stars pattern in from google chrome

Question

for (int i = 5; i >= 1; i--)
{
    for (int j = 0; j < i; j++)
    {
        Console.Write("*");
    }
    Console.WriteLine();
}
Console.WriteLine("---------------------------");

That is the code I am trying to run.. but it is giving error :

Uncaught SyntaxError: Unexpected identifier.

How should I resolve it?

Um.. you are asking about javascript but posting what looks like Java (or C#) code... — Jeremy J Starcher, Jun 16 '16 at 16:18
@JeremyJStarcher you are totally right, Suraj P Patil- do you mean JavaScript or C#?? — user3378165, Jun 16 '16 at 16:21
This is C# code that you've posted. Are you trying to write it in JavaScript? Change `int` to `var` and change `Console.WriteLine` to `console.log`. — ManoDestra, Jun 16 '16 at 19:47

Javascript doesn't have a strongly typed type system.

Drop the int from the for loop, replacing it with var:

for (var i = 5; i >= 1; i--)

and, once you've also substituted Console.log for Console.WriteLine, all will be well.

Why the downvote? The unexpected identifier is the type that the OP specified. – Fus Ro Dah Jun 16 '16 at 16:20

I had a mistake, which I've now corrected. – Fitzwilliam Bennet-Darcy Jun 16 '16 at 16:22
`Console.log` should not be capitalized, it should be `console.log` otherwise you will receive: `ReferenceError: Console is not defined` – KevBot Jun 16 '16 at 16:30
After applying your suggestions it is giving one single star(*) output and saying "undefined" – Suraj P Patil Jun 16 '16 at 16:53

No need to declare the vartype in the for, simply use

for (i=5;i>=1;i--){ }

Try using

console.log();

You should use var in the declaration of `i` in the loop. But at least you caught the incorrect use of `console` – KevBot Jun 16 '16 at 16:14
it is still giving error : Uncaught ReferenceError: Console is not defined at :5:12(anonymous function) – Suraj P Patil Jun 16 '16 at 16:28
@SurajPPatil Because it's `console`, not `Console`. Javascript is case-sensitive. – Barmar Jun 16 '16 at 16:55

Both of the other answers here neglect to include an important point. Indeed you should get rid of int, but it should be replaced with var, otherwise you are declaring global variables and populating the global scope with stuff it doesn't need. Generally bad practice.

For loops should look more like this:

for (var i=5;i>=1;i--){ }

`console.log`, not `Console.log` – Brennan Jun 16 '16 at 17:09

There is no a type declaration in JavaScript nor Console.Write or Console.WriteLine, it's not c#!

Change it to console.log and declare the variables with var:

for (var i = 5; i >= 1; i--)
     {
      for (var j = 0; j < i; j++)
          {
           Console.log("*");
          }
      Console.log();
     }
Console.log("---------------------------");
