<ul id="list"></ul>
<script>
const contacts = [{ name:"Priya", company:"Acme", stage:"lead" },{ name:"Raj", company:"Beta", stage:"won" }];
function render() {
const stage = document.getElementById("stage").value;
document.getElementById("list").innerHTML = contacts
.filter(c => c.stage === stage)
.map(c => `<li>${c.name} — ${c.company}</li>`).join("");
}
document.getElementById("stage").addEventListener("change", render);
