javascript - JSON.stringify - Strange behaviour with backslash in array -

i playing js while noticed strange behaviour backslash \ inserted string within array printed using json.stringify(). of course backslash used escaping special chars, happens if need put backslash in string? use backslash escape you're thinking, doesn't work json.stringify

this should print 1 backslash

array = ['\\'];  document.write(json.stringify(array));

this should print 2 backslashes

array = ['\\\\'];  document.write(json.stringify(array));

am missing something? considered bug of json.stringify?

it correct. json.stringify return required string recreate object - string requires escape backslash, return required escape backslash generate string properly.

try this:

array = ['\\']; var x = json.stringify(array) var y = json.parse(x) if (array[0] == y[0]) alert("it works") 

or

array = ['\\']; if (json.parse(json.stringify(array))[0] == array[0]) alert("it works")
