Challenge: Console Tigers with Loops

Task

Implement a for loop that outputs the word "Tiger" exactly 5 times.


              12345
            
let tiger = "___";

___ (let ___ = 0; i < ___; ___) {
  console.log(___);
};

The output should be:

python

Begin by assigning the value "Tiger" to the variable tiger.
Utilize the for keyword to create the loop.
Initialize the counter variable i.
Set the range for the counter i to go from 0 to 4 (5 loop iterations: 0, 1, 2, 3, 4).
Include the increment operation (++) for the i counter.
Place the tiger variable inside the console.log() function.


              12345
            
let tiger = "Tiger";

for (let i = 0; i < 5; i++) {
  console.log(tiger);
};

Everything was clear?
