The tap function is a higher-order function that takes two arguments: an input value and a callback function. The input value is passed to the callback function, and the result of the callback function is discarded. The input value is then returned by the tap function.

Here's an example of how to use the tap function in TypeScript:

index.ts
const value = 10;

const result = tap(value, (x) => {
  // This callback function will be called with the value 10.
  console.log(`The value is ${x}`);
});

console.log(`The result is ${result}`);
// Output:
// The value is 10
// The result is 10

In this example, the tap function takes the value variable as input and logs a message to the console using a callback function. The result of the tap function is then assigned to the result variable and logged to the console.

Note that the tap function does not modify the input value, but the callback function can perform side effects like logging or modifying external state.
