How can I write a multiline string into a file without adding characters to the string?

Question

I have a JavaScript function where I'm trying to write a PowerShell script to a PowerShell file. This is the function:

const script = 
`$Win32Product= Get-WmiObject -Class Win32_Product | Where Name -like 'Test Client'
if ($Win32Product -eq $null){$Check=$false}else{$Check=$true}
$Hash = @{ Check = $Check }
Return $Hash | ConvertTo-Json -Compress`;

const writeStringToPowerShellFile = () => {
    const blob = new Blob([script], { type: "text/plain" });
    const url = URL.createObjectURL(blob);
    const link = document.createElement("a");
    link.download = "resultScript.ps1";
    link.href = url;
    link.click();
};

Forget about whether or not the script itself makes sense, the issue is that when I do this the ps1 file comes out with " and \n all in one line and basically just messes up the powershell command. How do I make sure that the content of the file looks exactly like this:

$Win32Product= Get-WmiObject -Class Win32_Product | Where Name -like 'Test Client'
if ($Win32Product -eq $null){$Check=$false}else{$Check=$true}
$Hash = @{ Check = $Check }
Return $Hash | ConvertTo-Json -Compress

Don't use JSON.stringify, because you're dealing with a string, not an object.

Try replacing:

const fileData = JSON.stringify(script);
const blob = new Blob([fileData], { type: "text/plain" });

with:

const blob = new Blob([script], { type: "text/plain" });
