Construct an escaped string [duplicate]

Question

I am looking for an alternative api in javascript for the StringEscapeUtils in java.

Basically it should be able to convert

input string:

He didn't say, "Stop!"

output string:

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

Can we do the same using any underscore or any other util functions?

In underscore`s escape api,

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

returns

"&quot;test&quot;"

But I wanted in the format \"test\"'

So basically all you want to do is replace " with \" ...? — C3roe

Use JSON.stringify?

console.log(JSON.stringify('Hello "world"').slice(1, -1));

If you just want to replace " with \", you can do this:

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

If you want to escape other characters too, you can do something like this:

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

Both examples are using RegExp replace, just different regular expressions used.
