• Trigger JavaScript events like clicks or input changes.

• Modify the DOM before parsing the response.

• Avoid long-running loops or infinite scripts — they may cause timeouts.
• Escape special characters properly when sending code inside JSON.
• You can combine this with if, scroll, click, or type for dynamic control flows.
