How do I use jq to convert number to string?

Question

Given the following jq command and Json:

[
  {
    \"number\": 3,
    \"string\": \"threee\"
  },

The jq command has the tostring function. It took me a while to learn to use it by trial and error. Here is how to use it:

jq -r '.[] | [ .string, .number|tostring ] | join(": ")' <<< '
[{ "number": 9, "string": "nine"},
 { "number": 4, "string": "four"}]
'
nine: 9
four: 4
