How to add or update registry keys?

I have a Powershell script that reads content from JSON file and adds registry values. My script works well if the key in the registry exists. How can I make it to create the key if it doesn't exist, and then insert a value to it?

Powershell:

$jsonFile = "c:\temp\story\test2.json"
$customObject = Get-Content $jsonFile | ConvertFrom-Json

$customObject.PSObject.Properties | ForEach-Object {
    [void]( New-ItemProperty -LiteralPath $_.Value.path -Name $_.Value.name -Value $_.Value.value -PropertyType $_.Value.type -Force)
    }

Json:

{
    "reg1": {
        "path": "HKLM:\\SOFTWARE\\Clients\\test",
        "name": "test",
        "value": "0000",
        "type": "String"
    },
    "reg2": {
        "path": "HKLM:\\SOFTWARE\\Clients\\test",
        "name": "test2",
        "value": "111",
        "type": "String"
    }
}

You can use Test-Path to test if the registry path exists or not.

Get-Content -Path 'c:\temp\story\test2.json' -Raw | ConvertFrom-Json | ForEach-Object {
    foreach ($reg in $_.PSObject.Properties.value) {
        if (!(Test-Path -Path $reg.path)) { $null = New-Item -Path $reg.path -Force }
        $null = New-ItemProperty -Path $reg.path -Name $reg.name -Value $reg.value -PropertyType $reg.type -Force
    }
}
