https://training.uplatz.com/online-it... this JavaScript tutorial by Uplatz you will learn about Comparison Operations, Built-in Functions, and Looping in JavaScript.

Comparison operations, built-in functions, and looping are essential concepts in JavaScript programming. Here's an overview of each of these topics:

Comparison Operations: In JavaScript, you can compare two values using comparison operators such as "==" (equal to), "!=" (not equal to), "greaterarrow" (greater than), "greaterarrow=" (greater than or equal to), "lessthanarrow" (less than), and "lessthanarrow=" (less than or equal to). These operators return a Boolean value (true or false) based on the comparison result.

Built-in Functions: JavaScript provides several built-in functions that you can use in your code. For example, the alert() function displays a message in a popup window, the console.log() function outputs a message to the browser console, and the prompt() function displays a message and prompts the user for input. Other commonly used built-in functions include Math.random(), Math.floor(), parseInt(), and parseFloat().

Looping: Looping is a way to repeat a block of code multiple times. JavaScript provides several looping constructs, including the for loop, the while loop, and the do...while loop. The for loop is used to execute a block of code a specific number of times, while the while and do...while loops are used to execute a block of code repeatedly as long as a certain condition is met.
