How to Add HOST file Entry using PowerShell?

Here is the nifty PowerShell script to add HOST file entry using PowerShell:
$HostFile = 'C:\Windows\System32\drivers\etc\hosts'

# Create a backup copy of the Hosts file
$dateFormat = (Get-Date).ToString('dd-MM-yyyy hh-mm-ss')
$FileCopy = $HostFile + '.' + $dateFormat  + '.copy'
Copy-Item $HostFile -Destination $FileCopy

#Hosts to Add
$Hosts = @("intranet.Crescent.com", "Intranet", "mysite.crescent.com")

# Get the contents of the Hosts file
$File = Get-Content $HostFile

# write the Entries to hosts file, if it doesn't exist.
foreach ($HostFileEntry in $Hosts) 
{
    Write-Host "Checking existing HOST file entries for $HostFileEntry..."
    
    #Set a Flag
    $EntryExists = $false
    
    if ($File -contains "127.0.0.1 `t $HostFileEntry") 
    {
        Write-Host "Host File Entry for $HostFileEntry is already exists."
        $EntryExists = $true
    }
    #Add Entry to Host File
    if (!$EntryExists) 
    {
        Write-host "Adding Host File Entry for $HostFileEntry"
        Add-content -path $HostFile -value "127.0.0.1 `t $HostFileEntry"
    }
