You don't need to feel bad, it's pretty common to get a bit confused when it comes to using double quotes within double quoted strings, especially when string concatenation (combining strings with +) is involved.

It can be hard to visually decipher in the beginning, but like most things it becomes easier as you see more examples of it and get used to using it on your own.

Interfere with what? I'm not sure I understand the question, the second quote mark simply marks the end of the string.

When you use double quotes to start a string JavaScript will be looking for another double quote to indicate that the string is finished. If you want to include a double quote within the text of the string without making JavaScript think the string is finished you have to escape it with the \ symbol.

That means that in the example you provide the first double quote will be treated as pure text, which is inserted in the string, while the second will be treated as a marker that the string is finished. That is the intended outcome.
