join two arrays into 1 array [closed]

I created arrays .push like this

netPurchArr.push({
    netPRchRAw: formatCurrency(tst),
    netKurang: formatCurrency(ntKrng)
});

and result

    [
       {
          netPRchRAw: "3,565,980",
          netKurang: "958,020"
       }
    ]
[
   {
      netPRchRAw: "2,348,264",
      netKurang: "253,724"
   }
]

can join this array be like this

[
    {
        netPRchRAw: "3,565,980",
        netKurang: "958,020"
    },
    {
        netPRchRAw: "2,348,264",
        netKurang: "253,724"
    }
]
