One of the most common things you will want to do with a variable is to print a string representation of it. That’s what the toString() method is for. This article will explain when and how you can use it. Converting to Strings Data is displayed on your computer screen is most frequently displayed as text strings, regardless of how the data was stored. Numbers, arrays, boolean values, and objects, all have string representations that allow them to be viewed as text on screen, either for the … Read more

This article will show you how a JavaScript while loop is constructed, and what it us used for, with code examples. While loops are one of the simplest kinds of loops, and appear in most programming languages. A while loop runs a block of code repeatedly, until a condition is met. When the while condition is met, the loop stops. It’s important to get comfortable with using loops – and understanding how they work – as they form the backbone of just about every game and application you might write. Make sure you’re familiar … Read more

You’ve searched for ‘JavaScript Print’ – so you’re probably trying to output data to the console, to the webpage or to a printer. Here’s how to do all three. Printing to the Console with console.log() The JavaScript console.log() method prints data to the JavaScript console (visible in your browsers web inspector). Any type of data can be logged to the console, including strings, numbers, arrays, and objects, and either the contents of, or a text representation of, the value will be displayed. console.log() is frequently used for debugging – developers use it to view … Read more

This article will explain how to use escape characters to escape quotes in strings in the JavaScript programming language, with some examples. What is a String Variable in JavaScript? A string is a type of variable. It represents a series of zero or more characters. Other variable types are numeric, boolean, and array variables. A variable’s type defines what values it can hold and what can be done with it. For example, string variables can be split and joined to form new strings, and numeric variables can have mathematical operations … Read more

This article will show you how a JavaScript do while loop is constructed, and what it us used for, with code examples. do while loops are one of the simplest kinds of loops, and appear in most programming languages. A do while loop runs a block of code repeatedly, until a condition is met. When the do while condition is met, the loop stops. It’s important to get familiar with using loops – and understanding how loops work – as they form the backbone of just about every game and application you might … Read more

This brief tutorial will show you two ways to convert JavaScript arrays to strings using the toString() and join() methods. What Are Arrays? An array is a data structure which holds multiple values. It’s like a numbered list – each item in the array has a value and a position (called the index). The indexes start counting at position 0, so the first item in an array is at index 0, the second at index 1 and so on. Converting Arrays to Strings in JavaScript There are many reasons you may wish … Read more

This short tutorial will show you how to use the JavaScript Array.shift() method to remove items from an array, and provide some code examples. JavaScript Arrays An array is a variable type which can hold zero or more values within it. Each value in an array has a position, called the index – which is an integer value representing the items position in it’s order of appearance. Indexes start counting at position 0 – so the first item in an array is at index 0, the second item at index 1, and so on. JavaScript … Read more
