Practicing JavaScript can be challenging for beginners. Thankfully, there are many resources that offer a variety of exercises and projects to help beginners get started.
Whether you want to create a simple calculator or a tic-tac-toe game, there is something for everyone. Several coding platforms offer interactive courses and coding challenges for learners to practice javascript exercises for beginners .
Variables
In any programming language, variables are used to store information. They are an essential part of coding applications, and JavaScript is no exception. JS variables can be of different data types, including string, integer, and boolean. They can also be re-assigned, which allows them to change their type. JS also has several comparison operators, which can be used to make decisions or loops.
In a JS variables exercise, you will be required to multiply and divide data values, alert the results, and use assignment operators. In addition, you will learn how to set and get the value of a variable.
Online resources such as BitDegree Learn offer a range of JavaScript practice exercises, and they provide solutions for both beginners and advanced users. They include a number of quizzes and tests that can help you track your progress. Some sites also feature a code editor, so you can tinker with the examples and try them out for yourself.
Functions
If you're interested in learning the language that makes web pages interactive, you can try a variety of beginner JavaScript projects. Practicing these projects multiple times will help you learn practical skills and improve your speed. You can also use websites like CoderByte, which contains a variety of coding challenges that will help you work through different concepts and pieces of syntax. Then, you can compare your answers with others' to see how far you have come.
You'll also need to understand how functions work in JavaScript. Functions are a way of writing a block of code that can be called and executed multiple times. This includes a function that takes two inputs and returns an output.
Comparison Operators
A comparison operator compares two expressions and returns a boolean value, such as true or false. It is the most commonly used logical operator in JavaScript.
There are a number of online platforms that offer JavaScript practice exercises, from beginner to advanced. Many of these exercises are interactive and allow you to work through a program without being interrupted. Others are more like coding challenges that require you to complete a set of tasks.
CoderByte is one of the more popular platforms that offers a wide range of JavaScript practice exercises, including both interactive courses and traditional coding challenges. The site also saves your learning progress and lets you track your progress over time. It’s a great way to learn how to use JavaScript. There are even some introductory exercises that are perfect for beginners to help them establish a solid foundation. Then, as you advance you can tackle more challenging projects. You can also find a variety of practice problems in PDFs or on text-based websites.
Arrays
Arrays are data structures that enable you to access multiple values or elements at once using a single variable. They are used when a large number of similar values are needed to be accessed frequently or stored in a single place. In JavaScript, unlike in other programming languages, there is no special treatment of arrays when it comes to the comparison operator ( == ). The same rules apply as for any other object.
Moreover, an array can be nested, meaning that it contains other arrays as its elements. For example, the cargoHold array from Exercise 2 could contain the strings 'water,space suits,food,plasma sword,batteries'. You can use the splice method to add or remove elements in an array without changing its original size. For instance, if you need to replace the 'instruction manual' item from the final cargoHold array, you can do it by splicing it with 'keys'. You can also use splice to sort an array.
