If you have a string, you can split it twice:

var s = "2015:1.5 2016:1.5 2017:1.5 2018:15 2019:1";

console.log(
  s.split(" ").map(x => x.split(":"))
);

If you have an object, use Object.entries to convert it to an array:

var obj = {2015:1.5, 2016:1.5, 2017:1.5, 2018:15, 2019:1};

console.log(Object.entries(obj));

var year = [2015, 2016];
var data = [1.5, 1];

console.log(
  year.map((y, i) => [y, data[i]])
);

You can use Object.keys() and array#map

const obj = {2015:1.5, 2016:1.5, 2017:1.5, 2018:15, 2019:1};

var result = Object.keys(obj).map((key) => [key, obj[key]]);

console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }
