Hello World,
I am having a hard time running JavaScript in ATOM.io . I downloaded the script package and I am still unable to run a javascript code (alert(“hello world”)
through Atom.
I looked at videos and I do not know what I am missing.
Do I need to write in and console.log (…) for javascript to run properly?
Do I need to change the save file as .js not .html ?
Thanks for the help everyone.
You can use the Console to code Javascript in realtime to update your website as needed.
In Google Chrome you can go to the three gray buttons in the top right corner and then navigate to More tools and then to Developer tools. The Console tab can then be selected.
The console.log function writes a message to the console.
You can utilize the Document Object Model to change the contents through the console.
Hello @asteriskWorldChamp, hope you are great.
Now would you mind to use these topics for coding questions? I can help you with your code issue, also would be great if you share the code there.
You can use the “Preformatted Text” Button to encapsulate any kind of code you want to show.
function formatText(){
let words = “I’m a preformatted Text box, Please use me wisely!”
}
If you have any more questions, please let us know so we can help you!
