javascript – How does it work and how do the parameters of a function work?

Question:

How does it work and how do the parameters of a function work?

var form = document.getElementById('form');

function mifuncion(t,r) {
  console.log('Sip');
}

<form id="form">
  <input type="text" id="dato1" required>
  <input type="text" id="dato2" required>
  <button onclick="mifuncion(event)">Enviar</button>
</form>

Answer:

Well, first you have to know that a "function" is a piece of code that does a specific function or task.

A basic example is a mathematical calculation. Look at this function:

function sumar( a, b){
    console.log(a + b)
}

This function for it to work, it needs 2 parameters which are a and b (2 data or variables) for it to work

Let's call a function passing it the parameters:

sumar( 1, 2)

This what it will do is add 1 + 2 and it will show you the result in the console

Let's see another example: I'm going to make a function that repeats a code for me according to the number of times I pass the function through parameters

function repetir( repeticiones ){
    for ( var i = 1; i <= repeticiones; i++){
        console.log('repeticion numero' + i)
    }
}

we call the function

repetir(4) // repetira el codigo 4 veces
repetir(1000) // repetira el codigo mil veces
