I'm doing a chess game. So, I want to create

constructor {
// to initiate all placement, colors etc... of units
}

// something to say how a queen moves

// something to say how the king moves
etc... for all units...
}

how to do this ?

Hi NoxFly

I think you maybe looking for something like this (ES6):

class Rook {
constructor(colour) {
this.x = 0; this.y = 0; this.type=colour //Your state variables
}
//class methods
move(direction) {
// given the input directions, move the player according to the rules of the piece
}

rook1= new Rook("black");
rook2=new Rook("white");
rook1.move("foward");

You just to need to be careful that JS classes are really syntactic sugar on JS Functions, so private methods and data are not there (you need to use Closures). And Inheritance is not quite the same as other languages (Prototype inheritance).

JS inverts the relationship between functions and classes.
Classic Classes are data that carries behaviour (methods)
whereas JS Functions are Behaviour that carries data.

I recommend c++ or java for games/applications.

for ES6 code I am using the 2nd link
see code: https://code.sololearn.com/WTvhHZWRgMan/

for non-ES6 code I am using method 1.2 from the 1st link

You may want to consider using typescript to implement your js in an object oriented manner
