The console.log() method writes a message to the console.The console is useful for testing purposes. While the write() method writes HTML expressions or JavaScript code to a document. The write() method is mostly used for testing: If it is used after an HTML document is fully loaded, it will delete all existing HTML.

document.write("this is write"); console.log("this is log"); Copy paste in javascript section of html code and see the effect

document.write will override everything in the screen to print the value(s) you passed to it. console.log will display values in the js console (note that in a real browser you actually have to open the console in "inspect element"). So the console is not something that you will show to the users... It depends on what your program will do.

document.write() gives new learner a feel of how JS affects the DOM of the page. As a developer however I advise to use the methods of console. Not only log() exists but many others and each has it's own helpful function
