What is meant by Browser-API in react js? Broswer API in useEffect Hooks?
This means the Browser Javascript API, meaning any Javascript methods that interact with the browser, like finding elements on the page, fetching data, setting cookies etc.
Please see here for more info.
I assume you are talking about this page?
// Update the document title using the browser API
document.title = `You clicked ${count} times`;
They're not implying you have to use the browser APIs, just that in this example they are to set the page title.
Hope that makes it a bit more clear

Since a year and a half I am trying to figure out how some websites update their content in real time without AJAX method.
Please see this example website: https://pro.btcturk.com/en/basic/exchange/BTC_TRY
That website is changing many texts within content in different timing.
It means that when the server is updated with new values in the database then the website is listening to database changes and then reflecting/delivering inside content without ajax calls.
Can someone give an example how to achieve such functionality possibly using Javascript or PHP normal hand-code appreciated?
Thank you
You can see the process here:

what type of technique could i use for get this
please help me
The frames can't communicate directly but you can communicate via a server you control. This server can be on any domain.
You can push events using AJAX and receive events using server-sent-events. Make sure you're dealing with the cross domain requests appropriately by implementing CORS on the server.

I'm trying to do something kind of like Google's embeddable pdf viewer except I want to be able to embed a website and be able to view that on my website.
Specifically because I have many different teachers and they all use something called Planbook for their assignments, so I want to be able to view all of them at once. Also, I think it would help some other students.
So, does anyone know of a way to do this?
A quick way to acheive this is to use the HTML iframe. It displays a frame of another webpage, an example usage is <iframe src="http://www.w3schools.com"></iframe>. Also see this link for some more basic info.

I am making an open-source addon for firefox and chrome called and I am wondering if there is a way to control an email service like yahoo using javascript?
You can control the look of the page and probably (although I cannot be sure) send and edit messages without having to use the on-page buttons, but you cannot do server-side stuff such as logging into an account from a page without a log-in on it or sending a message from a page other than the email sending page. If you have any specific questions about controlling one specific thing, please add them in the comments, and I may answer them.

I'm attempting to scrape a site that has a split second javascript delay.
I'm currently using python for scraping. Whenever I 'get' the page, the javascript delay has not finished and is has not completely loaded the new dom yet.
How would I scrape such a pge?
You can extend Mozilla to build a web scraper which can leverage the full power of the web browser. After all data have been loaded and the DOM has been built, you can extract needed data from the DOM using XSLT. If the DOM was dynamically changed after initial loading, you can take some approaches to wait for the changes. Visit http://www.gooseeker.com for more information. GooSeeker publish a similiar tool free for everyone. Most of codes are in javascript and readible, from which you can find how it runs.
