What is the array in JavaScript? Arrays are used to store multiple values in a single variable. This is compared to a variable that can store only one value. Each item in an array has a number attached to it, called a numeric index, that allows you to access it. In JavaScript, arrays start at index zero and can be manipulated with various methods.
What is a const in JavaScript? In JavaScript, `const` means that the identifier can't be reassigned. (Not to be confused with immutable values. Unlike true immutable datatypes such as those produced by Immutable. js and Mori, a `const` object can have properties mutated.)
What is a var in JavaScript? var is the keyword that tells JavaScript you're declaring a variable. x is the name of that variable. = is the operator that tells JavaScript a value is coming up next. 100 is the value for the variable to store.
If you want to find out what the Array is you can do the following down below:
var myArray = [["this is the first position", 11], ["the second position, 22"]];
console.log(myArray[0]); and the answer will be [ 'this is the first position', 11 ]
Iff you want to find out what the Array is you can do the following down below:
var myArray = [["this is the first position", 11], ["the second position, 22"]];
console.log(myArray[1]); and you the answer will be [ 'the second position, 22' ]
If you want to see the object you can do the following down below:
var myArray = [["this is the first position", 11], ["the second position, 22"]];
console.log(typeof myArray[0]); and you will see the word object.
