Template strings in JavaScript.
Template were introduced in ES6 to allow embed expressions inside a string. Instead of ‘’ or “” quotation marks they use the backticks (``). They offer a much better way of string interpolation and expressions can be embedded in a way like ${a+b}. It offers a much nicer syntax than the + operator.

<style>
body {

}
.result {

}
</style>
</head>
<body>
<h1>Template strings in JavaScript</h1>
<div class="result"></div>

<script>
let resEle = document.querySelector(".result");
let a = 22;
let b = 44;
function add(a, b) {
return a + b;
}
document.querySelector(".Btn").addEventListener("click", () => {
resEle.innerHTML = `The sum of ${a} and ${b} = ${add(a, b)}`;
});
</script>
</body>
</html>Output
On clicking the ‘CLICK HERE’ button −
