Javascript Practice 15: JS Hero - Logging

 

Question: 

Write a function log that logs 'Hello Console!'. If you are working with a desktop browser, open the developer tools to see the output there as well.

Answer: 

function log() {

return 'Hello Console!'; 

}; 

console.log(log());

> This is a function declaration & not a function expression 

> name of the function: log

> parameter: () no parameter

> statement: return 'Hello Console!'; enclosed in curly brackets

> the function must have a return statement that specifies the value to return

> used the console.log method to display Javascript values in the browser

> console.log is a function in Javascript

> usually console.log is used for debugging purposes

> if a function is passed to console.log(log()), then the function console.log() will display the value of the passed function() in the console - Hello Console!
