1. What do arrays allow us to do?

An array can store multiple separate pieces of data in the same variable and can be indexed as follows eg.

x[0] x[1] x[2]

Arrays are useful in loops as the index notification can be easily incremented to move through the data.

2. What index should you use in order to access the first element in an array?

[0]

  • An array allows us to stores a sequence of values that are all of the same type.
  • Also an array allows us to quickly access each individual value.

I can save multiple items of the same type within a array.

  1. What index should you use in order to access the first element in an array?

To access the first element within a array, then you need to get the 0th position.
I.E.:
var myArray = new Array(“obj1”, “obj2”, “obj3”);
console.log(myArray[0]);

1- What do arrays allow us to do?

Arrays alow us to put many values into a single variable.

2- What index should you use in order to access the first element in an array?

İndex 0

#171
  1. Arrays allow us to store a set of variables of the same type.
  2. 0; call it by this format: anArray[0]; The index of array elements (same as characters in a string) is assigned position starting from 0, up to length of array minus 1.

1.To store multiple values in single variable
ex: var fruits=[“apple”, “orange”, “mango”]

  1. for accessing 1st element of an array we should use 0 index
    ex: fruits[0]

    var [0]

#177
  1. What do arrays allow us to do?

var nameofvariable = new ARRAY [“0”,“1”,“2”, etc]

You can take out the new ARRAY thing if you use the square brackets thing.

Arrays allow us to assign multiple values to one variable using the aformentioned format. Each of the assigned values has an ordered ID number to it, starting with 0.

  1. What index should you use in order to access the first element in an array?

Always start with 0.

#178

What index should you use in order to access the first element in an array?
colors[0]
