Getting much output from the number of user input in Javascript

Question

In Python I use "for x in range(j)" and j is defined from user input, for example

j = int(input())
for x in range(j)
print(j)

if I input j as 3, the output will be

3
3
3

My question is, how do i do it with javascript?

I tried to do it with array, etc. Nothing seems to work, sorry im really new at coding and need to learn 2 programming language for my college

Answer 1

You can do it with prompt function

const printData = () =>{

  let num = prompt("Please input a number", "3") // second parameter is the default value
  if(isNaN(num)){
    console.error(`${num} is an invalid number`)
    return
  }

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

printData()
