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(___);
};
copy

The output should be:

  1. Begin by assigning the value "Tiger" to the variable tiger.

  2. Utilize the for keyword to create the loop.

  3. Initialize the counter variable i.

  4. Set the range for the counter i to go from 0 to 4 (5 loop iterations: 0, 1, 2, 3, 4).

  5. Include the increment operation (++) for the i counter.

  6. Place the tiger variable inside the console.log() function.


              
12345

            
let tiger = "Tiger";

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