repeat a number n times

  • 772

This is what I have of the code, but I don't understand what I have wrong in the code.

function fakeBinary(size) {
  // La funcion llamada 'fakeBinary' recibe como argumento size(tamaño) que es un numero (entero)
  // y debe devolver un string de 1s y 0s con el tamaño indicado.
  // siempre empieza por 1
  // Por ej:
  // fakeBinary(10) devuelve "1010101010"
  // fakeBinary(3) devuelve "101"
  // Tu código aca:

     var array = [];
      size.map().forEach(element =>{
        if(element == size.repeat(n)){
          array.push(1);
        }else{
          array.push(0);
        }
      });
    return array.slice(1);
    }

    I don't understand why you put it in an array. Just concatenating on a string should already get rid of that problem.

    you can do it like this

    function fakeBinary(size) {
  let strFakeBinary = '';
  for (let i = 0; i < size; i++) {
    strFakeBinary += i % 2 == 0 ? '1' : '0';
  }
  return strFakeBinary;
}
console.log(fakeBinary(10))
console.log(fakeBinary(3))
