Array.some() method in JavaScript

by Sai gowtham1min read

The some( ) method executes the callback function on each element present in the array and returns true immediately if at least one element passes the test condition otherwise it returns false.

const users = [

    { id:1,user:"gowtham"},
    {id:2,user:"king"},
    {id:3,user:"nick"},
]


console.log(users.some(user=>user.id === 2)) //  true


console.log(users.some(user=>user.id === 10)) //  false

To check whether an email is available or not.

.

const emails = [
     "example1@gmail.com",
     "example2@gmail.com",
     "example3@gmail.com",
]



console.log(emails.some(email=>email === "example3@gmail.com")) // true

console.log(emails.some(email=>email === "example10@gmail.com")) // false

Note: The some() method executes the callback function until it finds the truthy value otherwise it returns false.
