Secondly, sometimes you may need a little more flexibility, which arrays provide. This is both inefficient, as more looping is done than needs to be, and makes the code less readable.

When looping through objects with the for.in loop, you must check if the property belongs to the object using hasOwnProperty(), as shown in the example above. The for.in loop works great, but it has a flaw in that it iterates through properties in the Prototype chain, which has many other properties besides the user's. This results in: Index: 0, firstName: John Suppose we have an object which contains a user details: let user = `) Unfortunately, JavaScript objects are not iterable like arrays or strings, so we can't just loop an object using map(), forEach() or a for…of loop. Window.When writing JavaScript code, you may need to loop through JavaScript objects and enumerate their fields/values. Var startScreen = document.querySelector('#startScreen') This hasn't worked though obviously, and I am feeling quite lost as to the correct step to accomplish the desired effect. So essentially using an if statement for each side of the array shape, and if the circle is moving in the direction of collision, they won't be able to move. I was trying to use if statements to detect collision before moving and repeat it for each side (see javascript lines of code 174-199). To be honest I am quite new to all of this, so I do not have a lot of trial and error experience since it is built off of guesses. I am having trouble creating collision detection between the randomly generated interior walls and the player so that the player is unable to pass through these walls. Using JavaScript, HTML, and CSS, I am trying to make a game in which, with limited visibility, the user must search for the exit (a white rectangle on the edges of the screen) while avoiding ghosts and interior walls (for the sake of ease of use, the canvas is completely visible so you can see what I am referring to). I am new to coding, and especially new to trying to make a game.
