Estimated read time 1 min read

Here is an example to create a simple “Hello” and “Goodbye” function in JavaScript:

function sayHello(name) {
  console.log("Hello, " + name);

function sayGoodbye(name) {
  console.log("Goodbye, " + name);


This code defines two functions, sayHello and sayGoodbye, which take a name parameter and log a greeting to the console. The last two lines of the code call the functions, passing in the argument "John".
