The main problem related to the Page load event is that it can be used to inject malicious code into a web page. This can be done by loading a specially crafted web page in an iframe or by using an exploit to inject script into a web page. This can allow attackers to execute arbitrary code on the victim’s computer, steal data from the victim’s computer, or even install malware on the victim’s computer.
window.onload = function() {
// code goes here
};
This code line is saying that when the window loads, the function will run.
Fibonacci
In mathematics, Fibonacci is a sequence of numbers in which each number is the sum of the previous two. The sequence starts with 0 and 1, and goes on forever.
In JavaScript, Fibonacci can be represented using the function fib() . This function takes two arguments: a number and its previous value. It returns the next number in the Fibonacci sequence if it’s already known, or else it returns the current value of fib(n-1)+fib(n) .
Here’s an example that prints out the first 10 Fibonacci numbers:
console.log(fib()); // 0, 1, 1, 2, 3, 5, 8, 13, 21, 34
Sequences
Sequences are a powerful feature of JavaScript that allow you to create and manipulate collections of data. Sequences can be used to create lists, arrays, and other data structures.
A sequence is an ordered collection of values. You can create a sequence by using the Array constructor or by using the range operator.
You can access individual elements in a sequence by using the index property. You can also use the slice operator to access specific elements in a sequence.
You can also use the push and pop operators to add and remove elements from a sequence, respectively.
