When it comes to web development, two of the most popular programming languages are Javascript and PHP. Both have their own advantages and disadvantages, so it can be difficult to decide which one is the best choice for your project. In this article, we’ll compare Javascript and PHP to help you make an informed decision.
Javascript is a scripting language that runs on the client side of a website. It is used to create interactive web pages and dynamic content.
Compiled language vs Scripting language Compiled code is faster than scripts with order of magnitude. Even after using a Just-in-time (JIT) compiler for PHP 7.4 and PHP 8 , PHP still slower than Go. Go is a clear winner.
Concurrency Go has concurrency as a built-in first class citizen. But PHP is good old language with no concurrency or parallelism in mind. The parallelism is achieved by executing scripts as a different process.
Javascript is a scripting language, created to run in the Internet browser but later used in all places!. Javascript is always shortened as js or JS.
Javascript Syntax: Variables // declare a variable var ourName; // store values myNumber = 5; myString = "myVar"; // declare variables with the assignment operator var myNum = 0; // add, subtract, multiply and divide numbers myVar = 5 + 10; // 15 myVar = 12 - 6; // 6 myVar = 13 * 13; // 169 myVar = 16 / 2; // 8 // increment and decrement numbers i++; // the equivalent of i = i + 1 i--; // the equivalent of i = i - 1; // decimals var ourDecimal = 5.
If you want to shutdown your Windows PC from your Python code, just use this code snippet.
import os os.system("shutdown /s /t 1") That’s it. I hope this helps. Do you recommend reading this blog post? share it!

First, “web development” is a very broad term and might, therefore, mean a lot of things including server-side rendered HTML pages, JSON APIs, microservices, etc.
Second, let’s define what makes a programming language qualify for web development. (sorted by importance)
Ecosystem Tooling Libraries Developer market Success stories Maintainability Language design Ecosystem consistency Performance Asynchronous execution for increased throughput Low latency Raw number-crunching performance Infrastructure Hosting and deployment Memory usage and cost in general So, let’s get ready to compare!
This is a bash shell scripting which can be found on Unix, Linux and Mac. You can install bash on the Linux subsystem on Windows too.
The first line is #! /bin/bash because the bash program is in /bin/bash, you can know the path where the bash is by this command which bash.
Print data or text on the screen You can use echo Hello, World! or echo "Hello, World".
