How to optimize a set to a buffer array?

• 0
  Good afternoon!
  Have a question about code optimization.
  
  The goal is to understand how to reduce the amount of code in Example 1, without significantly affecting performance.
  
  Branchmark: https://jsben.ch/OsKbY
  Setup:
  

  let data1={test:new Float32Array(50000)}
  let data2={test:new Float32Array(50000)}
  
  
  function setBuffer(name, figure_num, data_p){
  
    let num = 5 * figure_num
    let buffer_array = data1[name]
    for (let i = 0, l = data_p.length; i < l; i++) {
      buffer_array[num + i] = data_p[i];
    }
  }

  
  
  Example 1:
  

  let pt1=[1,2]
      let pt2=[3,4]
      let status=5
      for(let i=0;i<10000;i++){
        let buffer_array = data2['test']
        let num = 5*i;
        buffer_array[num+0] = pt1[0];
        buffer_array[num+1] = pt1[1];
        buffer_array[num+2] = pt2[0];
        buffer_array[num+3] = pt2[1];
        buffer_array[num+4] = status;
  
      }

  
  
  Example 2:
  

  let pt1=[1,2]
  let pt2=[3,4]
  let status=5
  
  for(let i=0;i<10000;i++){
    setBuffer('test', i, [pt1[0],pt1[1],pt2[0],pt2[1],status])
  }
