JSON将字符串数组字符串化时，引号上的双反斜杠

Question

I'm trying to stringify a JSON object that contains a string with quotes inside of it:

array = ['bar "foo"']

However, the string is created as: '["bar \\\\"foo\\\\""]' when I was hoping for something more along the lines of '["bar \\"foo\\""]'. Why are there two backslashes generated? Thanks

Answer 1

Why are there two backslashes generated?

Because backslashes must be escaped by backslashes to represent one single backslash in a string literal.

The string

'["bar \\"foo\\""]'
// or
"[\"bar \\\"foo\\\"\"]"

represents the value

["bar \"foo\""]

which is JSON for an array object containing the string value bar "foo" .

Probably the confusion was caused when you expected to see the value but the tool you used for that printed the string literal.
