Programmers often use the phrase “Hello, World!” as a simple way to test a new programming language or a new feature in an existing language. This is because the phrase is simple and easy to understand, and it allows programmers to see if their code is working as expected. When a programmer writes a program that prints “Hello, World!”, it is a way of confirming that the programming language is installed and set up correctly, and that the programmer is able to write and run basic programs in that language. Additionally, the phrase has become somewhat of a tradition in the programming community, so saying “Hello, World!” is a way for programmers to pay homage to that tradition.
