how to get drop down of month and set default value as current month (also in year) in angular js?

I have a two dropdown of Month and Year. The dropdown of year has 10 options from 2105-2025. While Open html page how can i set default value of current year and current date?

For example Today is May 2019. So for today I can put the value of vm.Search.Month = 3; and vm.Search.Year=2019; but doing this i have to change the value of vm.Search.Month and vm.Search.Year every month and year. How can I set the default value so i dosen’t have to change its value??

//this is the dropdown in angular for Date
vm.monthList = [

            { Value: 1, Text: 'Jan' },
            { Value: 2, Text: 'Feb' },
            { Value: 3, Text: 'Mar' },
            { Value: 4, Text: 'Apr' },
            { Value: 5, Text: 'May' },
            { Value: 6, Text: 'June' },
            { Value: 7, Text: 'July' },
            { Value: 8, Text: 'Aug' },
            { Value: 9, Text: 'Sep' },
            { Value: 10, Text: 'Oct' },
            { Value: 11, Text: 'Nov' },
            { Value: 12, Text: 'Dec' }
        ];



//Similarly this is the drodown for Year in angular JS
vm.yearList = [
            { Value: 2015, Text: '2015' },
            { Value: 2016, Text: '2016' },
            { Value: 2017, Text: '2017' },
            { Value: 2018, Text: '2018' },
            { Value: 2019, Text: '2019' },
            { Value: 2020, Text: '2020' },
            { Value: 2021, Text: '2021' },
            { Value: 2022, Text: '2022' },
            { Value: 2023, Text: '2023' },
            { Value: 2024, Text: '2024' },
            { Value: 2025, Text: '2025' }
        ];
