This guide assumes that you understand the fundamentals of web development, such as how to use JavaScript to add interactivity to a page.

Format console messages

You can use the format specifiers to format the console messages.

Format specifiers begin with a percent character (%) and terminate with a "type character" which indicates the type of data (integer, float, etc.).

For example,

Enter the following console command.

const tools = 'Chrome DevTools';
console.warn('%s is awesome.', tools);
