how do we increasing variable count using a foreach loop in JavaScript

Question

I am trying to run a foreach loop to keep looping into the var number is reached. I also need to keep track of the index. so far what I have tried

const data = ()=>{
    const myNumber = input.getPortCount() // Example currently this will be output a number 0 - 9
    foreach(i == 0, i => myNumber ++i){
         return console.log('i equals', i)
    }
}

I need I to increase by 1 start at 0 into it equal to the number of the variable myNumber

It seems like you are trying to do a for loop! for (var i = 0; i < myNumber; i++) { console.log('i equals', i) } forEach are for array looping — user3051780

You should go learn about loops. You need here the for loop and not foreach.... but you have more mistakes. here is the loop you need:

for (var i = 0; i <= myNumber; ++i){
     console.log('i equals', i);
}

This is syntax for forEach array, used on arrays :

array.forEach(function(currentValue, index, arr), thisValue)
