var strIn = '1234-12-34 05:27:56Z';var strOut = '';var regex = /\d{4}-(\d{2})-(\d{2}) (\d{2})/;​​

Tests:

var month = strIn.slice(5, 7);
var day = strIn.slice(8, 10);
var hour = strIn.slice(11, 13);

 
var month = strIn.slice(5, 7);var day = strIn.slice(8, 10);var hour = strIn.slice(11, 13);

var [_, month, day, hour] = strIn.match(regex)

 
var [_, month, day, hour] = strIn.match(regex)

var month = strIn[5] + strIn[6];
var day = strIn[8] + strIn[9];
var hour = strIn[11] + strIn[12];

 
var month = strIn[5] + strIn[6];var day = strIn[8] + strIn[9];var hour = strIn[11] + strIn[12];
