Reducing array to simple format : I have array of 

    [
    0: "United States"
    1: "India"
    2: "Germany"
    3: "Brazil"
    4: "Taiwan"
    5: "Israel"
    6: "United Kingdom"
    ]

I just want to make it like

    ["United States", "India", "Germany".....]

I already tried some codes like 

> .reduce(), .flat(), or .concat()

 but still not working
