Console Tips and Tricks

Here are some quick commands for the console.

Getting to the console in your browser

Press F12 and Find the console tab.

That little blue > there is the console. this is in brave or chrome, but on different browsers the shortcut to get there may be in settings. 

What can we do in the console?

The most common thing to do here is check for script errors, but you can do tons more things like run javascript functions or anything the browser is capable of if you know the commands. 

Test some variables

Log some variables to the console. 

Javascript

var test = 10;
var another_test = "kruxor";
console.log(test);
console.log(another_test);

Log as an object to see the variable name and value by adding {} to the variable name. 

Javascript

console.log({test});
console.log({another_test});


Example Console Result

Or you can just log them all together creating a single object.

Javascript

console.log({test}, {another_test});


Example logging multiple objects in one log.

You can then use the console.table to show the data in a tabular format rather then just the raw objects.

Javascript

console.table({test});
console.table({another_test});


Example of console.table result.

Other types of console messages

Here are some other message options in red and orange and just normal console message format. 

Javascript

console.log("This is a log message") // normal log
console.info("This is information") // another way to do a standard display
console.error("This is an error message") // highlight the message in red and flag it as an error
console.warn("This is a warning") // highlight the message in orange and flag it as a warning


Example console messages

Javascript

// Log some variables to the console. 
var test = 10;
var another_test = "kruxor";
console.log(test);
console.log(another_test);

// Log this as an object so you can see the variable name and value.
// just add some curly bracers to the main variable name. 
console.log({test});
console.log({another_test});

// Or you can just log them all together creating a single object.
console.log({test}, {another_test});

// You can then use the console.table to show the data in a tabular format rather then just the raw objects.
console.table({test});
console.table({another_test});

// Other types of console messages.
console.log("This is a log message") // normal log

Our brains are wired to find things we are looking for - if your always cynical or waiting for things to go wrong, then your life will reflect that. On the other hand, having a positive outlook on life will bring you joy and provide you with inspiration when you least expect it ☀️🍉🌴
