What is the method for ensuring a variable returns a number and not a function?

I've encountered a perplexing issue that I can't seem to solve. What could be causing the code below to output a function instead of a number?

let second = function(){ 
    return 100
};

console.log(second);

Answer №1

To actually run the function, you need to include () at the end.

console.log(second());

If you don't include the parentheses, you are simply referencing the variable second, which holds a function. In JavaScript, you use parentheses to invoke or execute a function.
