When is the best time to send a request to change the text in an input?

Question

JavaScript

There is an input field, the user enters data into it and this data is sent to the server on the go.
The question is, at what event to send data? Only onBlur or OnChange comes to mind.
But in the first case, the data may be sent too late, and in the second, a lot of requests have to be sent.

Answer 1

Call submit in onChange. Google towards the implementation of debounce, for example, lodash has it.

Answer 2

onInput, wrap in desired timeout
