What is a javascript function declaration?



  • Function Declaration

    The function declaration is saying what the function is going to do. We later call the function, this is when it gets executed.

    Below is a syntax for a function declaration.

    function functionName(parameters) {
    // code to be executed
    }

    Example of a function declaration.

    function myNumbers(a, b) {
      return a + b;
    }
    

    Using the function declaration.

    let sum = myNumbers(5, 5)
    console.log(sum)
    
    function myNumbers(a, b) {
      return a + b;
    }
    

    Result.
