    </svg>
  </div>
  <div class="boxs2">
    <span>Bottom Section</span>
  </div>
</body>

Step-2: Add CSS in<style>…</style> tag on index.html file.

.titles{
  font-size: 84px;
  font-weight: 500;
  padding: 100px;
}
body{
  text-align: center;
}
.boxs1, .boxs2 {
  width: 100%;
  border: 1px solid #eee;
  background: #ddd;
}
.boxs1 span, .boxs2 span {
  font-size: 68px;
  display: block;
  margin: 100px;
}
.stroke-svg{
  margin-bottom: 150px;
}
.arrows-arrows{
  visibility: hidden;
  opacity: 0;
}

Step-3: Add jQuery in<script>…</script> tag on index.html file.

In this animation,

First I have declared the scrollPos variable, and this variable gets the window scroll position.
Then, I have declared svgpos1 variable, in this variable is getting section top position.
I have subtracted 300 from the position of the section in the svgpos1 variable because I want the position 300px earlier than the top position of the section.
Then, I have declared svgpos2 variable, In this variable in I add svgpos1 value + 100
Then, I have declared svgpos3 variable, In this variable in I add svgpos2 value + 100

The animation will start when scrollPos position and svgpos1position are the same and the animation will end when scrollPos position and svgpos3 position are the same.

On scroll, I have reduced the stroke-dashoffset in the path.

jQuery(window).on('scroll', function () {
      var scrollPos = jQuery(this).scrollTop();
      var svgpos1 = jQuery(".boxs1").offset().top - 300;
      var svgpos2 = svgpos1 + 100;
      var svgpos3 = svgpos2 + 100;

      if(scrollPos > svgpos1 && scrollPos < svgpos2){
        jQuery(".first-arrows").css("stroke-dashoffset", 1155);
        jQuery(".second-arrows").css("stroke-dashoffset", 635);
        jQuery(".third-arrows").css("stroke-dashoffset", 850);
        jQuery(".fourth-arrows").css("stroke-dashoffset", 850);
      }else if(scrollPos > svgpos2 && scrollPos < svgpos3){ 
        jQuery(".first-arrows").css("stroke-dashoffset", 981);
        jQuery(".second-arrows").css("stroke-dashoffset", 485);
        jQuery(".third-arrows").css("stroke-dashoffset", 718);
        jQuery(".fourth-arrows").css("stroke-dashoffset", 680);
        jQuery(".arrows-arrows").css({"visibility":"visible","opacity":"1"});
      
      }else if(scrollPos > svgpos3){ 
        jQuery(".first-release-intelligence-animation-svg .arrows-arrows").css({"visibility":"visible","opacity":"1"});
      }
      else{
        jQuery(".first-arrows").css("stroke-dashoffset", 1460);
        jQuery(".second-arrows").css("stroke-dashoffset", 715);
        jQuery(".third-arrows").css("stroke-dashoffset", 985);
        jQuery(".fourth-arrows").css("stroke-dashoffset", 990);
        jQuery(".arrows-arrows").css({"visibility":"hidden","opacity":"0"});
      }	
    });
