Javascript Practice 13: JS Hero - What is x?

 

Question: 

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

function whereIs (name) {

  return 'Where is ' + name + '?';

}

let x = whereIs ('Jacky');

Answer: 

'Where is Jacky?'

> This is a function declaration & not a function expression 

> name of the function: whereIs (camelCase)

> parameter: () parameter is name

> statement: return 'Where is ' + name + '?'; enclosed in curly brackets

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

> the value type in this case is a string

> strings can be used with single or double quotes

> we can concatenate the string with a '+' sign

> declared a variable x and initialized it with a value

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

> in this case the argument 'whereIs (name)' is 'whereIs ('Jacky')'

> the value will be 'Where is Jacky?'
