How can I convert a hash into JavaScript format?

Question

I have a hash

{:name =>"[email protected]"}

I am trying to convert this hash into the following JavaScript format.

{"name" : "[email protected]"}

I tried:

{:name=>"[email protected]"}.to_json

which gives the output:

"{\"name\":\"[email protected]\"}"

Parsing it with JSON gives:

JSON.parse({:name=>"[email protected]"}.to_json) 
# => {"name"=>"[email protected]"}

`"{\"name\":\"[email protected]\"}"` is the `inspect` of the string, the default way strings are presented in console. The string *content* (escaped by backslashes by `inspect`, which is why you may have thought the result to be wrong) is: `{"name":"[email protected]"}`, exactly what you want. use `puts {...}.to_json` instead of just `{...}.to_json` in console to verify this. — Amadan, Feb 16 '17 at 04:14

to_json should work:

require 'json'
{:name =>"[email protected]"}.to_json
#=> "{"name":"[email protected]"}"

What I understand is that you want to recreate the same hash that you converted to JSON.

This could be done by passing option symbolize_names: true to JSON.parse method.

The code would look something like this

JSON.parse({:name=>"[email protected]"}.to_json, symbolize_names: true)
