Script Preparation code:

var directAddresses = [];
for(var i=1; i< 100; i++) {
  directAddresses.push(`${i}deliverymanage@direct.com`);
}

var mySetDomains = new Set();
for(var i=1; i< 10000; i++) {
  mySetDomains.add(`${i}direct.com`);
}

var usingArrayDomains = [];
for(var j=1; j< 10000; j++) {
  usingArrayDomains.push(`${j}direct.com`);
}

Tests:

Array
_.map(directAddresses, (da) => { const domain = da.split('@')[1]; _.includes(usingArrayDomains, domain); });
Set
_.map(directAddresses, (da) => { const domain = da.split('@')[1]; mySetDomains.has(domain); });
