JavaScript External Javascript calling functions from another external javascript file external javascript call in html,external javascript call function,external

So, I've looked at other questions like this and they haven't really answered the questions.

In short: I've worked with HTML, Java, VB, and whatever language MIRC uses(it's been a little under 10 years).

I'm new to javascript, but because of my other computer language know-how's... I know that using Java, I can create class's and class-like functions.

But, with html/javascript, I'm not sure how to call a function from one external .js file to another.

Let's say: I want to make a player class that I can call functions from anytime and use it in the 'main' .js file that uses those functions from that class inside another function. For example.

If I had

function isDead() {
if (health < 10 || energy < 10)
{
return dead = 'true';
    }
    else { return dead; }
}

in Player .js file, and in the main one, I had.

function fight() {
if (isDead() == 'true')
{
    energy -= 10;
     health -= 10;
    Swords();
}


document.getElementById("energy").innerHTML = energy;
document.getElementById("health").innerHTML = health;
document.getElementById("sword").innerHTML=sword;

}

In the item.js I had

var swordDamage = 0;

function Swords(){
if (swordDamage < 3)
swordDamage +=1;
else
return sword -=1;
}

(Mind you this actually worked (I haven't tested the swords() yet as I just made it for this question.)

Is there any particular way I need to call upon the functions from other .js files into the main.js file.

example: main.function();

or am I better off saving them as an html document and writing nothing but script to get around this?

Thanks for answering!
