Let and Var - block versus function scope

var letTest = function() {
    var fsc = 1; // functionScope
    console.log(fsc); // 1
    let x = 31; // blockScope
    if (true) 
    {

      let x = 71;  // andere variable da neuer blockScope
      console.log(x);  // 71
      fsc = 4;
      console.log(fsc); // 4
    } // ende Block
    console.log(x);  // 31
    x = x *2;
    console.log(x);  // ??
    console.log(fsc); //
  }
