Question 212819 in Javascript Question posted in
A very good W3school tutorial can be found here.

Javascript – I am trying to check if every element of one array is in another array

1 – I am using the below code to verify if every element of one array is present in another array.

     let expected_ActionLinks = ["Add to Call List", "ChangeOwner","this","Edit","Delete","Sharing","MI/User Reg",
     "Convert","Disqualify","Email Preferences"]

     let actual_ActionLinks = ["Add to Call List", "ChangeOwner","Edit","Delete","Sharing","MI/User Reg",
     "Convert","Disqualify","Email Preferences"]



   try{ 

   
    
    if(expected_ActionLinks.some(async (element)=>{ actual_ActionLinks.indexOf(element) > -1 }))
    {

        console.log("All action links are present on the page")
        return true
    }

    else{

        console.log("All action links are present on the page")
        return false 

    }

}

I am trying to verify if every element of one array is present in the other array.
For example here – every element of expected_ActionLinks should be present in actual_ActionLinks. If yes, it will return true, if no it will return false.

The problem here is the above code returns always true irrespective of any situation. Please suggest

    Remove async add return

    function check() {
  let expected_ActionLinks = ["Add to Call List", "ChangeOwner", "this", "Edit", "Delete", "Sharing", "MI/User Reg",
    "Convert", "Disqualify", "Email Preferences"
  ]

  let actual_ActionLinks = ["Add to Call List", "ChangeOwner", "Edit", "Delete", "Sharing", "MI/User Reg",
    "Convert", "Disqualify", "Email Preferences"
  ]

  if (expected_ActionLinks.some((element) => {
      return actual_ActionLinks.indexOf(element) > -1
    })) {

    console.log("All action links are present on the page")
    return true
  } else {

    console.log("All action links are present on the page")
    return false

  }
}

check()

    You can use .every of Array

    let expected_ActionLinks = ["Add to Call List", "ChangeOwner", "this", "Edit", "Delete", "Sharing", "MI/User Reg",
  "Convert", "Disqualify", "Email Preferences"
];

let actual_ActionLinks = ["Add to Call List", "ChangeOwner", "Edit", "Delete", "Sharing", "MI/User Reg",
  "Convert", "Disqualify", "Email Preferences"
];

const isSame = expected_ActionLinks.every(item => actual_ActionLinks.includes(item))

console.log(isSame)
