Window: setInterval() method
Baseline
Widely available
*
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
* Some parts of this feature may have varying levels of support.
Warning:
When the code parameter is used, this method dynamically executes its value as JavaScript.
APIs like this are known as injection sinks, and are potentially a vector for cross-site-scripting (XSS) attacks.
You can mitigate this risk by always assigning TrustedScript objects instead of strings and enforcing trusted types.
See Security considerations for more information.
The setInterval() method of the Window interface repeatedly calls a function or executes a code snippet, with a fixed time delay between each call.
