Javascript在一个索引中对多个值的数组进行排序

Question

I have an array with values

[[300, 2.6], [400, 2.2], [500, 3.0]]

How can I sort both dimensions such that I can display the output correctly in a graph?
array.sort() does not seem to work as it only sorts by one value in the entire array.

Thank you.

Your best shot is to use lodash :

 var values = [[500, 1.1], [300, 2.2], [400, 1.5]]; var sorted = _.sortBy(values, function(pair){return pair[0];}); console.log('sorted values: ' + JSON.stringify(sorted));
