Value cannot be passed from Javascript to EJS, so how can I achieve it with another way?

I can't put everything inside the EJS, I need to find a way to make this happen, any help appreciated, thank you.

for (let i = 1; i < 3; i++) {
        initializeSlider($(".slider-1"), [
                  <% let index = %> i
          "data:image/<%=posts[index].images[0].image.contentType%>;base64,\
           <%=posts[index].images[0].image.data.toString('base64')%>",
          "data:image/<%=posts[index].images[1].image.contentType%>;base64,\
           <%=posts[index].images[1].image.data.toString('base64')%>",
          "data:image/<%=posts[index].images[2].image.contentType%>;base64,\
           <%=posts[index].images[2].image.data.toString('base64')%>",
          "data:image/<%=posts[index].images[3].image.contentType%>;base64,\
           <%=posts[index].images[3].image.data.toString('base64')%>",
           "data:image/<%=posts[index].images[4].image.contentType%>;base64,\
           <%=posts[index].images[4].image.data.toString('base64')%>",
        ]);
     }

<% for (let i = 0; i < posts.length; i++) { %>
        initializeSlider($(".slider-<%= i+1 %>"), [
          "data:image/<% posts[i].images[0].image.contentType %>;base64,\
           <%= posts[i].images[0].image.data.toString('base64') %>",
