How to check if an Array with Object contains a Property

i’m coding a decentralized app and i’m stuck.
Here is my problem : i’m calling with async function and return an array with object :

const result = [
{ trait_type: "Neck Gear", value: "1" },
{ trait_type: "Alpha Score", value: "6" },
{ trait_type: "Generation", value: "Gen 0" },];

I need to access the line “Alpha score”. I have to check if alpha score exist in this object.
So i did this :

async function checkAlpha() {
    try {
        const checkAlphaTxn = await traitsContract.compileAttributes([4]) 
                    .then((result) => {
                        // console.log(result.hasOwnProperty("Alpha Score")) //return false
                        console.log(result) //return array above
                    })
    } catch (error) {
        console.log(error)
    }
}

I wanted to use the .hasOwnProperty() method but it returns to me FALSE. But alpha score value exist.

Thank you in advance for those who can unblock me ! 🙂
