Lodash: sorting an array of arrays [duplicate]

Question

I have an array of arrays of the following kind

let finalData = [[1920000000, 273.15], [1620033000, 276.15], [1627700000, 272.15]]

The first value inside the data array is the timestamp. How do I sort the entire array from smallest to largest timestamp, with or without lodash?

Expected result:

let finalData = [[1620033000, 276.15], [1627700000, 272.15], [1920000000, 273.15]]

Thank you in advance for your help

Have you tried finalData.sort()?

Using Array#sort:

const finalData = [[1920000000, 273.15], [1620033000, 276.15], [1627700000, 272.15]];
finalData.sort(([a], [b]) => a - b);

console.log(finalData);

Using lodash:

let finalData = [[1920000000, 273.15], [1620033000, 276.15], [1627700000, 272.15]];
finalData = _.sortBy(finalData, e => e[0]);

console.log(finalData);
