Autocompleting in the Code Editor

Autocomplete in the Code Editor allows parentheses and braces to be autocompleted while coding. You can activate this function in your Account Settings using the IDE menu on the left side. You can also choose to default to block view in the editor when possible. To learn more about block coding, check out our article here!

Autoformatting JavaScript Programs in the Ace Code Editor

Autoformatting is available in all CodeHS JavaScript programs in the Ace Editor. The formatter, Prettier, makes sure that all code conforms to a consistent style. Learn more about Prettier here.

Once this setting is turned on, the program will automatically format the code each time students save the program. To enable Auto-Format, click the gear icon in the upper left corner to access the Editor Settings and toggle the Auto-Format control under Editor.
