javacript array 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]);
}

Example 3: array javascript

special_dates = [];
special_dates.push(new Date('2021/02/12').getTime());
special_dates.push(new Date('2021/02/13').getTime());
special_dates.push(new Date('2021/02/14').getTime());

			
for (var i = 0; i < special_dates.length; i++) {
 console.log(special_dates[i]) ;
}

Example 4: javacript array

[element0, element1, ..., elementN]

new Array(element0, element1[, ...[, elementN]])
new Array(arrayLength)
