For step 2.1.1, we again just use a path substitution, with `,` that represents any single JSON value (null, boolean, number or string): `S/,/`.
For step 2.1.2, we want to check that it is either a value `,` or the beginning of an array or object so we use ``s/,|[`{[`]/``.
+The `|` subex operator will try the subexes on both sides of it and `[]` are used to recognise one of several options, in this case the options are the start of an object and the start of an array.
Once again we will want to run all of the step 2.2 commands only if both of these checks pass, so we add some more curly brackets for the step 2.2 commands after them: ``S/,/s/,|[`{[`]/{}``.
