What I did (in code):

    const character = 'a'
    const timesRepeated = 50
    let answer = ''

    for (let i = 0; i < timesRepeated; i++) {
       answer += character
    }

console.log(answer)
console.log(answer.length)

Logs: aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
Logs: 50

What I did (in English):

Assign the string 'a' to the variable character.
Assign 50 to the variable timesRepeated.
Assign '' (an empty string, i.e., a string with a length equal to 0) to the variable answer.
The for loop: Set the variable i to start at 0, run the loop as long as i is less than timesRepeated, and at the end of each iteration of the loop, increment i by 1. Each iteration of the loop, store answer + character in answer (i.e., update answer).
Log to the console answer.
Log to the console answer.length.
