Simple! You can convert it to a JSON (as a string).

var dictstring = JSON.stringify(dict);

To save a file in NodeJS:

var fs = require('fs');

fs.writeFile(thing.json, dictstring);

Also, objects in javascript use colons, not equals:

var dict = {one : [15, 4.5],

        two : [34, 3.3],

        three : [67, 5.0],

        four : [32, 4.1]};
