+The solution: `pattern:/"(\\.|[^"\\])*"/g`.
+
+Step by step:
+
+- First we look for an opening quote `pattern:"`
+- Then if we have a backslash `pattern:\\` (we technically have to double it in the pattern, because it is a special character, so that's a single backslash in fact), then any character is fine after it (a dot).
+- Otherwise we take any character except a quote (that would mean the end of the string) and a backslash (to prevent lonely backslashes, the backslash is only used with some other symbol after it): `pattern:[^"\\]`
+- ...And so on till the closing quote.
+
+In action:
+
+```js run
+let reg = /"(\\.|[^"\\])*"/g;
+let str = ' .. "test me" .. "Say \\"Hello\\"!" .. "\\\\ \\"" .. ';
+
+alert( str.match(reg) ); // "test me","Say \"Hello\"!","\\ \""
+```
