When we:
button_to with remote: true
.js.erb file corresponding to the requestThen the code in the js.erb file gets executed on the response.
I was curious as to how that code gets executed in the browser.
Is it through some sort of eval call in rails library, or is it related with the Content-Type header being set to text/javascript in the response?

Basic way to perform AJAX operation Note 1 : Be sure with the dataType used in the code, it could be of type ' json ' or ' text ' depending on the data that needs to be sent or operation to perform in the controller end. return render json: { random_param_name: “Random event created successfully!”} And that's it.
ajax returns immediately and the next statement, return result; , is executed before the function you passed as success callback was even called.
When you make an AJAX request, your browser sends an HTTP request to a given address. The server on the other end of the request responds, and returns the data to your browser. This is the same thing that happens when you navigate to a new web page.
It is executed, because the dataType of the ajax request is set to script.
$.ajax({
url: url,
dataType: "script",
success: success
});
