JavaScript Reference

Quick Reference

The console.trace() method displays a trace that shows how the code ended up at a certain point.

In the following, we would most likely call the function when the user clicks a button. This would then write the trace to the console for testing purposes.

// function to run
function my_function() {
    console.trace('My Test');
}

Output

My Test
my_function	@	VM56:4
onclick	@	page.php?filename=t…ref_console_trace:1

Syntax

console.trace(label)

Parameters

ParameterDescription
labelA label for the trace (optional)

JavaScript Notes:

  • When using JavaScript, single or double quotation marks are acceptable and work identically to one another; choose whichever you prefer, and stay consistent
  • JavaScript is a case-sensitive language; firstName is NOT the same as firstname
  • Arrays count starting from zero NOT one; so item 1 is position [0], item 2 is position [1], and item 3 is position [2] … and so on
  • JavaScript variables must begin with a letter, $, or _
  • JavaScript variables are case sensitive (x is not the same as X)

We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.
