const util = require('@scode/utilities');

// cut off decimal places to a specified point
util.truncate_decimal(12.345678, 2);

util.try_parse_json('{{foo');

// copy an object to prevent modification of the original
const obj = {foo:'bar'};
const copy = util.copy_object(obj);
copy.foo = 'baz';
console.log(obj.foo); // bar

// run a regular expression and get a callback for every result
