I want to write google chrome extension code. but what I want to do is read the data of a site and intervene according to that data. For example, if a product is on sale on Amazon, if I type it with a command, will it automatically get it? I would like to emphasize that I will not take it, it has to take it automatically with the command I gave, so will it be able to take it by itself while I sleep? Is this possible with a java script?
