Download JavaScript Cheat Sheet
Here you can go with the quick guide or JS cheat sheet which will help you to know more
about shortcuts and tricks:
To include javascript code on a page, the syntax is – 
<script type = “text/javascript”> 
// all the code 
</script>
To create separate �le, use extension .js and include the �le on the page as – 
<script src="myjsfile.js"></script>
Comments Single-line Multiple-
line
There are two types of comments: // this is a single line
comment /* this is a multiple line comment when you have to
write a lot of things */
Variables – values that hold
data to perform calculations or
other operations
var – most widely used. can be accessed within the
function where declared. can be reassigned. 
const – constant value i.e. cannot be reassigned
let – can be used only within the block its declared, can be
reassigned
Data types
Can be of di�erent types –
Number, eg. var id = 20
Unassigned variable, eg. var x
String, eg. var company = “hackr”
Boolean, eg. var windowopen = true
Constants. eg. const counter = 1
Operations, eg. var sum = 20 + 20
Objects, eg. var student =

A cheerful, full of life and vibrant person, I hold a lot of dreams that I want to ful�ll on my own. My
passion for writing started with small diary entries and travel blogs, after which I have moved on to
writing well-researched technical content. I �nd it fascinating to blend thoughts and research and
shape them into something beautiful through my writing. View all posts by the Author
