javascriptSort array of objects by specific property

var arr = [{prop: 3}, {prop: 1}, {prop: 2}];

`var arr` declares test array of objects to sort	`arr.sort` this function will sort an array by custom callback function and overwrite `arr` with sorted array
`function(a, b)` callback will get 2 array elements to compare: `a` and `b`	`a.prop > b.prop ? 1 : -1` will sort our array in ascending order of `prop` values
