In this
section, the thing to be discussed is about the tutorial of writing JavaScript.
But before it is discussed further, you are going to know first about the data
types in JavaScript. In JavaScript, type itself is kind of classification that
identifies one type of data among various types. Meanwhile, the data could come
in a lot of different types. JavaScript data structure consists of three main
data types. The first is type of primary data
which consist of string, number, and boolean. For other data types will be
explained below.
Let the Tutorial Begins: from Data
Types to Onclick Event

Know more about data types in JavaScript
In this
tutorial of writing JavaScript, you need to know the second data type called as
composite data types (composite/reference).
Composite data types are included as data types in which the reference
addresses store the variables. This kind of data types are also called as the
complex types. This type has more than one single components including objects
and array. Object in composite data types are defined as methods and properties
collection. Anything which is not primitive is called an object in JavaScript.

Use specification data types TDS
TDS stands
for Tabular Data Stream. It is the protocol of application layer which is used
for transferring the data between the client and database server. In
JavaScript, specification data types TDS or
stream table will help you to stream tabular data in large size and then filter
it. It will be able to provide you the rendering of tables or pages which will
be super-fast. There will be no more delays or waiting to load for page.
However, you should also notice that there is the problem with data tables. It
has the complex JavaScript option. Besides, it is also too heavy.
·
Learn arithmetic operator of JavaScript
The next tutorial
writing data script type JavaScript is that you should apply operator precedence computational of JavaScript.
In this case, you should learn it to at least get good understanding about it.
Like its name, arithmetic operators will perform the arithmetic in the form of
numbers whether it is variables or literals. Operator precedence itself will
describe the order of performed operations in arithmetic expression. There are
also the values of operator precedence in JavaScript.
·
Understand the function of onclick
The next is
about onclick function. Onclick is also
known as HTML attribute. To describe it, the onclick has onclick of event which
captures the event. The event to be captured comes from mouse button of users
on element in which onclick attributes are applied. Usually, this action will
show the result in the form of call to script method like JavaScript
function.
·
Apply the onclick event
Onclick event will occur when users click on the element. For example, this onclick
occurs to display current time, date, and day. By clicking on the element, it
can also change the text color. Besides, by clicking on one button, it could
copy certain text from a field into another field of input. This kind of
onclick could even be assigned to the object of window.
