JavaScript Fundamentals - Number

In this tutorial, you will learn about the JavaScript `Number` type and its useful methods for working with numbers effectively.

Introduction to JavaScript Number type

Besides the primitive number type, JavaScript also provides the `Number` reference type for numeric values.

To create a `Number` object, you use the `Number` constructor and pass in a number value as follows:

``````var numberObject = new Number(100);
``````

This example defined a `numberObject` with a numeric value of `100`.

To get the primitive value out of a `Number` object, you use the `valueOf()` method as follows:

``````console.log(numberObject.valueOf()); // 100
``````

To get a number value as a string, you use the `toString()` or `toLocaleString()` methods.

The `toString()` method accepts an optional argument that determines the radix in which to present the number. The radix (or base) is the number of unique digits that represent numbers in a positional numeral system.

For example, the decimal system uses ten digits from 0 through 9, therefore, the radix is 10.

See the following example:

``````var aNumber = new Number(10);
console.log(aNumber.toStrring()); // "10"
``````

In this example the `aNumber` has a primitive value 10, therefore, the `toString()` method returns 10 in the decimal system.

However, the following example returns the binary form of the `aNumber` variable.

``````console.log(aNumber.toString(2)); // "1010"
``````

If you call a method on a primitive number value, JavaScript will convert it into a `Number` object temporarily. This feature is called primitive wrapper types in JavaScript. For example:

``````let x = 10;
console.log(x.toString(16)); // "a"
``````

Introduction With Basic JavaScript

The world’s most misunderstood programming language is JavaScript but JavaScript is now used by an incredible number of high-profile applications. So, it’s an important skill for any web or mobile developer to enrich the deeper knowledge in it.

Unlike most programming languages, the JavaScript language has no concept of input or output. It is designed to run as a scripting language in a host environment, and it is up to the host environment to provide mechanisms for communicating with the outside world.

Its syntax is based on the Java and C languages — many structures from those languages apply to JavaScript as well. JavaScript supports object-oriented programming with object prototypes, instead of classes. JavaScript also supports functional programming — because they are objects, functions may be stored in variables and passed around like any other object.

Let’s start off by looking at the building blocks of any language: the types. JavaScript programs manipulate values, and those values all belong to a type. JavaScript’s types are:

· Number

· String

· Boolean

· Function

· Object

· Symbol

and undefined and null, which are … slightly odd. And Array, which is a special kind of object. Date and RegExp, which are objects that you get for free. And to be technically accurate, functions are just a special type of object. So the type of diagram looks like this:
