How to escape special characters in building a JSON string?

Question

Here is my string

{
    \'user\': {
        \'name\': \'abc\',
        \'fx\': {
            \'message\': {
                \'color\': \'red\'
            }

Most of these answers either does not answer the question or is unnecessarily long in the explanation.

OK so JSON only uses double quotation marks, we get that!

I was trying to use JQuery AJAX to post JSON data to server and then later return that same information. The best solution to the posted question I found was to use:

var d = {
    name: 'whatever',
    address: 'whatever',
    DOB: '01/01/2001'
}
$.ajax({
    type: "POST",
    url: 'some/url',
    dataType: 'json',
    data: JSON.stringify(d),
    ...
}

This will escape the characters for you.
