// Bad practice

1)  function x() { while (i < length) { let x = i; ... }  }

2) while (i < length) { x.y.z[i] = 'hello'; } 



// God practice

1) Do the loop outside func body. It's a slow wrapper anyways :)

    // Define 'x' outside the loop, else you need to reallocate memory for it 
    // on each run and assign
    let x = 0; while (i < length) { x = i; ... }

2) The 2 first members are static, so define them outside the loop

   let _static = x.y.z

   while (i < length) { _static[i] = 'hello'; }
