Quick Notes Based On "Learning JavaScript Exercise" Section of Frontend Masters' "Complete Intro to Web Development, v2"

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.

What I practiced:

  • Same as above.

What I learned:

  • From the above code, I didn't learn anything new.
  • For this section, there was no instruction outside of the exercise itself.

What I still might not understand:

  • Nothing for this section.
