// load math.js (using node.js)

const { complex, replacer, reviver, typeOf } = require('..')

// serialize a math.js data type into a JSON string

// the replacer function is needed to correctly stringify a value like Infinity

const x = complex('2+3i')

const str1 = JSON.stringify(x, replacer)

console.log(str1)

// outputs {"mathjs":"Complex","re":2,"im":3}

// deserialize a JSON string into a math.js data type

// note that the reviver of math.js is needed for this:

const str2 = '{"mathjs":"Unit","value":5,"unit":"cm"}'

const y = JSON.parse(str2, reviver)

console.log(typeOf(y)) // 'Unit'

console.log(y.toString()) // 5 cm
