Bit Manipulation Hacks | Brilliant Math & Science Wiki
In this wiki, we shall discuss a number of one liners that help us solve simple arithmetic problems in binary numbers. They are often found to be very useful (and quick) in larger programs. Because of the way numbers are represented in computers, these one liners are not only handy for the programmer but also very fast in execution. The Bitwise operators constitute the standard operators from ...

What is 3 to the 3rd power? – TheLinuxCode
Bit Manipulation for Power Calculations. As a programming expert, I find bit manipulation techniques particularly interesting for optimizing power calculations. For powers of 2, we can use left shift operations: # Calculate 2³ using bit shifting result = 1 << 3 # Equivalent to 2³ print(f"2 to the 3rd power using bit shift: {result}") # Output: 8

ECMAScript 2023 (ES2023 or ES14) introduces a fresh set of array instance methods to enhance the way arrays can be modified.. In total four new methods are added, toSorted() (vs sort()), toReversed() (vs reverse()), toSpliced() (vs splice()), and with (vs bracket notation). These methods use immutable operations on arrays, making it easier and more predictable to work with data without ...

just put it this way, whenever you want to do DOM manipulation on the client side, you're going to use JavaScript. I don't mind if it's with JavaScript, JQuery, or PHP, whichever is best. i don't think there's “best” when it comes to DOM manipulation, and out of these three php is a server-side technology, other than the other two.
