function loadScript(url) {
var index = window.document.getElementsByTagName("script")[0];

current I am showing the info window with the hardcoded text, I want to show it using a react component, how can I be able to do that?
i wrote another component, whenever the marker i want to show the react component dynamically
Thanks in Advance

One option to consider would be:
1) to create an instance of InfoWindow without setting content property at this stage:
const infowindow = new window.google.maps.InfoWindow({
content: ""
});
2) and set or update content dynamically via InfoWindow.setContent function once a marker is clicked:
marker.addListener("click", () => {
const content = ReactDOMServer.renderToString(InfoWindowContent);
infowindow.setContent(content);
infowindow.open(map, marker);
});
where InfoWindowContent is represented as a React element and ReactDOMServer.renderToString function is used to render it into HTML
string since InfoWindow.setContent accepts content value as a string:
const InfoWindowContent = (
<div id="bodyContent">
<p>
<b>Uluru</b>, also referred to as <b>Ayers Rock</b>, is a large sandstone
rock formation in the southern part of the Northern Territory, central
Australia. It lies 335 km (208 mi) south west of the nearest
large town, Alice Springs; 450 km (280 mi) by road. Kata Tjuta
and Uluru are the two major features of the Uluru - Kata Tjuta National
Park. Uluru is sacred to the Pitjantjatjara and Yankunytjatjara, the
Aboriginal people of the area. It has many springs, waterholes, rock caves
and ancient paintings. Uluru is listed as a World Heritage Site.
