How to fix Arguments for the rest parameter 'x' were not provided in TypeScript

// Function definition
function greet(greeting: string, ...names: string[]) {
  console.log(greeting + " " + names.join(", "));
}

// WRONG - missing required 'greeting' parameter
greet(); // Error: Arguments for the rest parameter 'names' were not provided

// CORRECT - provide the required parameter
greet("Hello"); // OK - rest parameter gets empty array
greet("Hello", "Alice", "Bob"); // OK - rest parameter gets ["Alice", "Bob"]

function processData(action: string, ...items: number[]) {
  console.log(`Action: ${action}, Items: ${items}`);
}

// WRONG - missing required 'action' parameter
processData(); // Error

// CORRECT - provide required parameter
processData("sum"); // OK, items = []
processData("sum", 1, 2, 3); // OK, items = [1, 2, 3]

// Option 1: Use optional parameter with ?
function logMessages(prefix?: string, ...messages: string[]) {
  const p = prefix ?? "LOG:";
  console.log(p, ...messages);
}

logMessages(); // OK - both optional
logMessages("INFO:"); // OK
logMessages("INFO:", "message1", "message2"); // OK

// Option 2: Use default parameter value
function formatOutput(separator: string = ", ", ...values: string[]) {
  return values.join(separator);
}

formatOutput(); // OK - uses default separator
formatOutput("; "); // OK - custom separator
formatOutput("; ", "a", "b", "c"); // OK - custom separator with values

// Old signature (still in your code)
function handleEvent(...args: any[]) {
  // implementation
}

handleEvent(); // This worked

// New signature (after update/refactor)
function handleEvent(eventType: string, ...args: any[]) {
  // implementation
}

handleEvent(); // Now this fails - need to provide eventType
handleEvent("click"); // Fixed

// Multiple overloads
function configure(options: object): void;
function configure(key: string, ...values: string[]): void;
function configure(keyOrOptions: string | object, ...values: string[]): void {
  if (typeof keyOrOptions === "object") {
    // handle options object
  } else {
    // handle key + values
  }
}

// WRONG - doesn't match any overload properly
configure(); // Error

// CORRECT - matches first overload
configure({ theme: "dark" }); // OK

// CORRECT - matches second overload
configure("theme", "dark"); // OK
