This decodeURIComponent() function decodes a Uniform Resource Identifier (URI) means it will remove all the escape sequences in the provided URI which was encoded using encodeURIComponent. See the code snippet:
<!DOCTYPE html>
<html>
<head>
<title>Welcome to LearnKode - A code learning platform</title>
</head>
<body>
<button onclick="decryptUriComponent()">Original uri component</button>
<p id="sample"></p>
<script>
function decryptUriComponent() {
var uri = "http://LearnKode.com/my page.asp?name=ståle&car=saab";
var enc = encodeURIComponent(uri);
var dec = decodeURIComponent(enc);
var result = "Encoded URI: " + enc + "<br>" + "Decoded URI: " + dec;
document.getElementById("sample").innerHTML = result;
}
