Example

// the file this example creates, in the system's temporary directory
// (Environment.getTempPath() does not include a trailing separator)
const path = `${Environment.getTempPath()}/testfile.txt`;

// try to create a text file
const writer = File.createText(path);
if (writer) {
    writer.writeLine("Line 1");
    writer.writeLine("Line 2");
    writer.writeLine("Line 3");

    // write() adds no line ending, so these three calls all land
    // on the same line
    writer.write("Line 4");
    writer.write(" - still on line 4");
    writer.writeLine(" - still on line 4");

    writer.writeLine("Line 5");

    // close() flushes the file to disk
    writer.close();

    alert(`Wrote ${path}`);
}
