Javascript Practice 11: JS Hero - What is x?

 

Question: 

Which value does x have after execution of the following code?

function reply(phrase) {

  return phrase;

}

let x = reply('How do you do?');

Answer: 

'How do you do?'

> This is a function declaration & not a function expression 

> name of the function: reply

> parameter: () parameter is phrase

> statement: return phrase; enclosed in curly brackets

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

> declared a variable x and initialized it with a value

> the value will be, the output we get when we 'call' the function reply with the argument

> in this case the argument 'reply(phrase)' is 'reply('How do you do?')'
