I am new to vscode and I come from a replit background. When I hover my mouse just to the left of a line number, a small red dot appears. When I click in the dot it then stays there until I click it again. I am confused on the purpose of this.

The red dots that appear by clicking on the left of the line or by pressing F9 on the current line are vscode breakpoints. They're used for debugging purposes
