Using the 'let' Function for Resource Management

The 'let' function can be particularly useful for managing resources, such as closing streams or files, in Kotlin. By using 'let', you can ensure that resources are properly handled in a concise way while maintaining readability. This is especially important in scenarios where you want to perform operations on a resource and ensure it gets released afterward.

code class FileReaderExample {
    fun readFile(filePath: String) {
        File(filePath).inputStream().use { inputStream ->
            inputStream.bufferedReader().use { reader ->
                val content = reader.readText()
                println(content)
            }
        }
    }
}
