The code outputs:
function
number
number
string
number
Explanation:
-
The variable
ais declared with a value of1, but then a function with the same name is also declared. In JavaScript, functions take precedence over variables with the same name, sotypeof areturns"function". -
The variable
bis declared, and then a function with the same name is also declared. However, the function is then assigned a value of1. Therefore,typeof breturns"number". -
The variable
cis declared as a function and then later assigned a value of1. Therefore,typeof creturns"number". -
The variable
dis declared with a value of1. Then, a self-invoking anonymous function is defined that changes the value ofdto'2'and also declares a function with the same name. However, since the function is defined within the scope of the anonymous function anddis changed to a string before the function is called,typeof dreturns"string". -
The variable
eis declared with a value of1. Then, a constant functionfis defined with the same name as the variablee. However, sincefis a function expression and not a function declaration, it does not affect the scope ofe. Therefore,typeof ereturns"number".
