Javascript Practice 17: JS Hero - Logging and Strings

 

Question:

 

Write a function shout that takes a string and returns this string duplicated. In addition, the return should be logged.

Example: shout('Fire') should return 'FireFire' and should log 'FireFire'.

 

 

 

 

Answer: 

 

function shout (string) {

let x = string + string;

console.log(x);
return x;

} 

> This is a function declaration & not a function expression 

> name of the function: shout

> parameter: () parameter string

> statement: let x = string + string, enclosed in curly brackets

> statement: console.log (x), enclosed in curly brackets 

> statement: return x, enclosed in curly brackets

> created a variable x using let

> concatenated the string parameter and stored it in x

> this function has console.log() to return the function in the console

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

> console.log is a function in Javascript

> usually console.log is used for debugging purposes

> in this case the function log, when called, returns / logs the value of the parameter in the console
