Today, the editor will share with you the relevant knowledge about what the original value of JavaScript is. The content is detailed and the logic is clear. I believe most people still know too much about this, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.

The original value refers to a value that has no property or method.

The original data type refers to the data that has the original value.

JavaScript defines five raw data types:

String

Number

Boolean

Null

Undefined

The original values are immutable (they are hard-coded and therefore cannot be changed).

Assuming x = 3.14, you can change the value of x. However, you cannot change the value of 3.14.

Value type comment

"Hello" string "Hello" is always "Hello"

3.14 number 3.14 is always 3.14

True boolean true is always true

False boolean false is always false

Null null (object) null is always null

Undefined undefined undefined is always undefined
