how to output the console.log in VSCode's terminal?

usually , the console.log will output in the browser's Inspect -> console . but I want to put them in VSCode's terminal or other place. because I'm debugging in a iOS device , and using the WKWebView. (use camera take a photo and pass to web). But I can't use Inspect in a WKWebView...

so can anyone tell me the right way to debugging(I want to check console.log) in a iOS device?
