Use filter to filter what you want to keep.

Like this:

const arr = [
            {
                games1: [
                    {
                        playername: '1',
                    },
                ],
            },
            {
                games2: [
                    {
                        playername: '1',
                    },
                    {
                        playername: '2',
                    },
                ],
            },
        ]

// keep games1

const newArr = arr.filter((r) => r.games1)
console.log(newArr)

        // remove games2, keep others
const newArr2 = arr.filter((r) => !r.games2)
console.log(newArr2)

output would be

[
    {
        "games1": [
            {
                "playername": "1"
            }
        ]
    }
]

const NewArray = array.filter((item) => item !== "games2");

console.log(NewArray)

Try the below code:

 let final = x.filter(x=>{
     let c = Object.getOwnPropertyNames(x)
    return c!="games2"
 })

here the output of the 'final' is :

[{

        "games1": [{
            "playername": "1"
        }]
    }
}]
