Array elements can be accessed through index number.
Index number starts from zero to array's property length minus one.
Here is an example:
var pets = ['cat', 'dog', 'rat'];
console.log(pets[0]);The above code will print the first element of pets array - string cat.
Array elements must be accessed through only using bracket notation.
Dot notation is invalid.
Valid notation:
console.log(pets[0]);Invalid notation:
console.log(pets.1);
Create a file named accessing-array-values.js.
In that file, define array food :
var food = ['apple', 'pizza', 'pear'];Use console.log() to print the second value of array to the terminal.
Check to see if your program is correct by running this command:
