How to wait for a promise within a loop block

-
JavaScript promises enable developers to write asynchronous applications in JavaScript Loops are ways of iterating elements For instance doing an asynchronous task within a for loop can be done as follows; Note that lag is used to emulate some delay. const items = [1, 2, 3, 4] const lag = async (delay) => {     return new Promise((resolve) =>         setTimeout(() => res(`${delay / 1000} sec`), delay)) } items.forEach(async (item) => {     const seconds = await lag(1000 * item)     console.log(seconds) }) expected output 1 sec 2 sec 3 sec 4 sec After running the code above every second some text was printed

JavaScript intro to classes

-
Classes are objects 'functions which introduce inheritance parent child relationship in JavaScript it promotes code reusability which reduces the amount of code in a JavaScript application. JavaScript class decelerations start with keyword class proceeded by class name with a class body having a constructor along with methods for instance class human {     constructor(name) {          this.name = name;          this.gender = null;     }     great() {         return "Greetings " +         (this.gender == "male") ? "mr " : "mrs " + this.name     } } Child classes are created by adding the keyword extends followed by the parent class name and parent class methods can be called using the syntax super.+"method name"(parameters) class man extends human {   ...

FlappingBird is a single player arcade-style game in which the player controls the bird, which moves persistently to the right. The player is tasked with navigating the bird through pairs of trees that have equally sized gaps placed at random heights. the bird automatically gravitates and only ascends when the player taps the touchscreen or spacebar. Each successful pass through a pair of trees awards the player one point. Colliding with a tree or the ground ends the gamepl...

How to make a html5 breakout game in JavaScript

-
In this tutorial i will walk through the  process of developing a simple breakout game in JavaScript using html5 canvas I'll be using craters.js a compact html5 game engine. in every step i will first explain the procedure in a less technical method later I'll include the snippets of the actual game , a link to the github repository and a live working demo. Game world is 2d space with zero friction and zero gravity in order to avoid applying acceleration to the entities periodically maybe this will be changed later. First entity is a ball an entity with zero friction that upon colliding with an obstacle such as a block, paddle or the the screen boundaries bounces back in the opposite direction the bouncing from left to the right side of the screen is implemented by if(position.x  + radius < 0) // bounce if(velocity > 0) return; // moving velocity *= -1; // change direction direction is only changed if the ball tries to move  beyond the zero position. i have t...
