A number representing positive infinity is called infinity. -Infinity stands for the opposite of infinity. When a number exceeds its maximum value, it enters infinity: 1.797693134862315E+308. When an integer crosses its lower bound, it enters infinity: -1.797693134862316E+308. The universal object has the quality of infinity and is a variable with a global scope, in other words. The number is the beginning value of Infinity. A Boolean value in JavaScript may either be true or false. Users can use the Boolean function to know if something is "true" or "false". Booleans can be kept track of and modified over time by ... Read More

In this tutorial, we will learn how we can get the coordinates of the mouse cursor relative to the screen with JavaScript. We will find the position of the cursor vertically (Y-axis) and Horizontally (X-axis) relative to the screen. JavaScript allows us to use two different properties to get the coordinates of the mouse cursor relative to the screen when the mouse button is pressed anywhere on the screen − Using the event.screenX Property Using the event.screenY Property Let us discuss both of them one by one with code examples. Using the event.screenX Property The event.screenX property is ... Read More
