Create a string that has been properly formatted

Question

I need a javascript alternative to the StringEscapeUtils in java, specifically for converting input strings like:

He didn't say, "Stop!"

The desired output format should be:

He didn't say, \"Stop!\"

Is there a similar function available in underscore or any other utility library?

Although underscore's escape API converts as follows:

var a = '"test"'; _.escape(a)

resulting in:

"&quot;test&quot;"

I actually require the format: \"test\"'

To transform " into \", you can implement the following:

var phrase = "He didn't say, \"Stop!\"";
console.log(phrase.replace(/"/g, '\\\"'));

If you wish to escape additional characters as well, you may try this approach:

var phrase = "He didn't say, \"Stop!\"";
console.log(phrase.replace(/("|'|\\)/g, '\\\$1'));

Both instances involve utilizing RegExp replace with distinct regular expressions.
