Learn JavaScript Step by Step Part 4 Control Flow

Part 4: Control Flow in JavaScript Welcome to the next part of our JavaScript journey! In this segment, we'll explore control flow in JavaScript. Control flow allows you to make decisions in your code and execute specific blocks of code based on conditions. It's a fundamental concept in programming. At the end of this blog you will get a quiz to test your understanding of this topic. Let's dive in! Conditional Statements: Making Decisions Conditional statements are used to make decisions in your code. They allow your program to take different actions depending on whether a certain condition is true or false. 1. If Statement:  The if statement is the most basic conditional statement. It executes a block of code if a specified condition evaluates to true. let age = 18 ; if (age >= 18 ) {     console . log ( " You are an adult. " ) ; } If you run the code in VS Code, the output will be: Output: You are an adult. 2. Else Statement:  You can use the else stateme

Learn JavaScript Step by Step Part 3 Basic Concepts

  Part 3: Basic Concepts of JavaScript Welcome back to your journey of learning JavaScript step by step! In this part we'll dive into the fundamental concepts that serve as the foundation of any programming language. We'll explain these concepts in a way that even a school-going student can understand. Variables: Containers for Information Variables in JavaScript are like labelled containers or Storage boxes where you can store different types of information. Imagin them as name tags on boxes, making it easy for you to find what you need. In JavaScript, you can create a variable like this: let myNumber ; In this example, we've created a variable named myNumber, but it's empty right now. Let's put something inside it: myNumber = 32 ; Now, myNumber contains the number 32. But befor you start declaring variables, it's essential to understand some rules. Rules for Declaring Variables in JavaScript Variable Names: Variable names (identifiers) must begin with a lett
