Millised on kaks viisi funktsioonide deklareerimiseks JavaScriptis?

There are two main ways to declare functions:

1. Function Declaration:

   // Function declaration with the name 'sum'
   function sum(a, b) {
     return a + b;
   }
   

2. Function Expression:

   // Function expression assigned to the variable 'subtract'
   const subtract = function(a, b) {
     return a - b;
   };
   

There is also a variant of the function expression - Arrow Function:

// Arrow function assigned to the variable 'multiply'
const multiply = (a, b) => a * b;
