VisualizaçõesWhy "Undefined" in Javascript?
I started learning JavaScript and I was doing some exercises. I got undefined in Mozilla console. I am just curious about whether or not I'm missing something. Here's what I did.
function myFunction () {
console.log("test call");
}
myFunction();

To return a value other than the default, a function must have a return statement that specifies the value to return. A function without a return statement will return a default value. In the case of a constructor called with the new keyword, the default value is the value of its this parameter. For all other functions, the default return value is undefined.
