How to add an item from foreach to object array in typescript?

In my Code I have below code snippet

const accountEnv = 'Prod'
const accPermissionMap = {}
Object.values(Accounts).forEach(account => { const adminRole = ImportableRole.fromRoleArn(this, `${account.account}-Role`, 'arn:aws:iam::' + account.account + ':role/Admin')})

As a result, Inside the foreach loop, it will assign below values to the "account" variable when the loop is running.

ImportableRole.fromRoleArn(this, `Prod-Role`, 'arn:aws:iam::' + Prod + ':role/Admin')
ImportableRole.fromRoleArn(this, `UAT-Role`, 'arn:aws:iam::' + UAT + ':role/Admin')
ImportableRole.fromRoleArn(this, `MT-Role`, 'arn:aws:iam::' + MT + ':role/Admin')
ImportableRole.fromRoleArn(this, `Dev-Role`, 'arn:aws:iam::' + Dev + ':role/Admin')

I'm trying to

1. Add every ImportableRole to "accPermissionMap" as an object with a key.

So, after adding, "accPermissionMap" should be something similar to,

{
Key: Prod,  Value: ImportableRole.fromRoleArn(this, `Prod-Role`, 'arn:aws:iam::' + Prod + ':role/Admin')
Key: UAT,  Value: ImportableRole.fromRoleArn(this, `UAT-Role`, 'arn:aws:iam::' + UAT + ':role/Admin')
Key: MT,  Value: ImportableRole.fromRoleArn(this, `MT-Role`, 'arn:aws:iam::' + MT + ':role/Admin')
Key: Dev,  Value: ImportableRole.fromRoleArn(this, `Dev-Role`, 'arn:aws:iam::' + Dev + ':role/Admin')
}

Could someone please suggest a workaround?

You can add each ImportableRole object to the accPermissionMap using the account.account as the key. Then, iterate over the keys of accPermissionMap and check if any of them match the accountEnv value. If a match is found, you can perform your desired action with the corresponding ImportableRole. Also, make sure you have the necessary import statements and that the Accounts object is defined correctly.

const accountEnv = 'Prod';
const accPermissionMap = {};

Object.values(Accounts).forEach(account => {
  const adminRole = ImportableRole.fromRoleArn(this, `${account.account}-Role`, 'arn:aws:iam::' + account.account + ':role/Admin');
  accPermissionMap[account.account] = adminRole; // Add each ImportableRole to accPermissionMap
});

// Check which ImportableRole item is equal to accountEnv
Object.keys(accPermissionMap).forEach(account => {
  if (account === accountEnv) {
    // If it matches, perform the desired action
    const matchedRole = accPermissionMap[account];
    // Do something with the matched role
    console.log(`Found a match for accountEnv (${accountEnv}) with role:`, matchedRole);
    // Perform your desired action with the matched role
  }
});
