const data= [
     { name: "name1",
       email: "[email protected]"},
     { name: "name2",
       email: "[email protected]"},
     { name: "name3",
       email: "[email protected]"},
]

const email = "[email protected]"

console.log(data.some(item => item.email === email))

returns true if found. replace some with find to get the first element that matches
