練習問題

リストなタプルをソートせよ。

サンプルコード

process.stdin.resume();
process.stdin.setEncoding('utf8');

var rowElements = [{"timestamp":"1728082796491"},{"timestamp":"1728083796491","name":"ai","publish":"ture","condition":"good","comment":"ok"},{"timestamp":"1728083845078","name":"aita","publish":"1","condition":"good","comment":"ok"},{"timestamp":"1728082865943"},{"timestamp":"1728360810390","name":"test","comment":"iine"},{"timestamp":"1728362175611","name":"test","comment":"good"},{"timestamp":"1728082597520"},{"timestamp":"1728362004019","name":"test","comment":"last"},{"timestamp":"1728361668285","name":"test","comment":"こんにちは"},{"timestamp":"1728361943212","name":"test","comment":"良いね"}];

console.log(rowElements)

var target = [];

var result = Array.from(rowElements).sort(function(line1, line2) {
    return (line1.timestamp < line2.timestamp) ? -1 : 1;
});


for(var i = 0; i < result.length; i++)
{
   target.push(result[i]);
}

console.log(target)
