I’ve long known about the JavaScript console, and use it sometimes for debugging. However, I didn’t know to use if for testing – until now.<\/p>\n
In the past, I’d build a rudimentary web page around a JavaScript function, sending the output to a div using innerHTML. However, for checking continuity and logic, sending output to the console might be simpler. Testing it today, I’d just open Notepad, type<\/p>\n
<script><\/p>\n
lines
\nof
\ncode
\nto be
\ntested<\/p>\n
console.log(<\/span>Output you want to see);<\/span><\/p>\n <\/script><\/p>\n then save the file as html and point the browser to it. Of course, at first, I’d just get a blank screen. F12 opens the developer tools, then clicking Console shows the output. <\/p>\n In the JavaScript code, the command<\/p>\n console.log(<\/span>Output you want to see);<\/span><\/p>\n sends the output to the console. If for some reason there’s a problem, you know right away: that’s what the console is there to tell you. Therefore, it’s a great testing utility.<\/p>\n HTH:)<\/p>\n Source:<\/p>\n w3schools<\/a><\/p>\n
