      8 console.log(str1)

     11 // deserialize a JSON string into a math.js data type
     12 // note that the reviver of math.js is needed for this:
     13 const str2 = '{"mathjs":"Unit","value":5,"unit":"cm"}'
     14 const y = JSON.parse(str2, reviver)
     15 console.log(typeOf(y)) // 'Unit'
     16 console.log(y.toString()) // 5 cm
