where would you type up the javascript?

Answer 1

What do you mean? Do you mean how to code in javascript if so just go to the code playground and choose html as your language

Answer 2

The Code Playground should be relatively easy to find in the website version of SoloLearn, but if you are in the app version, it can be accessed via the curly braces, green circle with plus sign to add a new project, then select the project type.

For HTML, CSS, and JavaScript, select Web for project type.
