declaring array in javascript code example
Example 1: list javascript
//Creating a list
var fruits = ["Apple", "Banana", "Cherry"];
//Creating an empty list
var books = [];
//Getting element of list
//Lists are ordered using indexes
//The first element in an list has an index of 0,
//the second an index of 1,
//the third an index of 2,
//and so on.
console.log(fruits[0]) //This prints the first element
//in the list fruits, which in this case is "Apple"
//Adding to lists
fruits.push("Orange") //This will add orange to the end of the list "fruits"
fruits[1]="Blueberry" //The second element will be changed to Blueberry
//Removing from lists
fruits.splice(0, 1) //This will remove the first element,
//in this case Apple, from the list
fruits.splice(0, 2) //Will remove first and second element
//Splice goes from index of first argument to index of second argument (excluding second argument)
Example 2: javascript array
//create an array like so:
var colors = ["red","blue","green"];
//you can loop through an array like this:
for (var i = 0; i < colors.length; i++) {
console.log(colors[i]);
}
