I need to loop in between index 2 and 7. How could I achieve it?

Answer 1

You can use a for ... loop as in the code below:

var myArray = ["a", "b", "c", "d", "e", "f", "g", "h"];

// i = 2 for the starting index
//until you reach index 7
for (var i = 2; i <= 7; i++) {
    console.log(myArray[i]);
    //Do something
}

If you want to replace the 7 by the last case in your array you can do:

var myArray = ["a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k"];

// i = 2 for the starting index
//until you reach end of the array
for (var i = 2; i < myArray.length; i++) {
    console.log(myArray[i]);
    //Do something
}
