envFileWriter.get("HELLO","NOT WORLD");// NOT WORLD BY DEFAULT

envFileWriter.set("HELLO","WORLD");

// note : unsaved changes are not readable with .get()

// persists the changes
await envFileWriter.save();
```

# Typescript example
```ts
import EnvFileWriter from "env-file-rw";
const envFileWriter = new EnvFileWriter< { HELLO : any} >("test.env",false); // you can specify the structure of the env file for the get()

// open the file and parse it
await envFileWriter.parse();

envFileWriter.get("HELLO","NOT WORLD");// NOT WORLD BY DEFAULT

envFileWriter.set("HELLO","WORLD");

// note : unsaved changes are not readable with .get()

// persists the changes
await envFileWriter.save();
