I\'m trying to save some string content into a file from JavaScript. Below is my code and I\'m getting issues because of new lines in the String content.

How to save a file with preserving new lines?

var text = \"Hello \\n World!\"
var file = new Blob([text], {{type:\'text/plain\'}});
var anchor = document.createElement(\"a\");
anchor.href = URL.createObjectURL(file);
anchor.download = \"file.log\";
anchor.click();

I\'m getting below error in my browser,

How do you load this code?
The error you\'ve shown in the screenshot makes it look like the \\n you\'ve shown in your code isn\'t really a \\n (an escape sequence, backslash followed by n which produces a newline in the resulting string), but an actual newline in the string literal, which is indeed a syntax error. But it\'s really not clear how you\'re getting from A (the code you\'ve posted) to B (the error in the screenshot). Could you clarify?
Note that in any case, the double curly braces in var file = new Blob([text], {{type:\'text/plain\'}}); are an error, it should be just var file = new Blob([text], {type:\'text/plain\'});.
