javascript - Uncaught SyntaxError: Unexpected token = in Chrome -

i following on-line tutorial create simple game in html using canvas , javascript. tried load seemed fine code nothing showing on screen , received error in console saying

uncaught syntaxerror: unexpected token =

this portion of code seems incorrect:

player = {         x: null,         y: null,         width: 20,         height: 100,          update = function() {},         draw = function() {             ctx.fillrect(this.x, this.y, this.width, this.height)         };     }; 

ps - error showing in chrome.

you using = signs in literal object definition, replace them :

    update : function() {},     draw : function() {         ctx.fillrect(this.x, this.y, this.width, this.height);     } 

as amtd specified in answer, error show after draw definition, because putting ; illegal token inside literal object definition
