Is Go better than PHP?

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! Ecosystem (it depends) Both PHP and Go have created huge web-development ecosystems but they are focusing on different goals.

Javascript Cheatsheet – Documentation and Code Snippets

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.
