This article mainly talks about "JavaScript string and numerical example Analysis". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "JavaScript string and numerical example Analysis".

JavaScript string

A string is a variable that stores characters, such as "BillGates".

The string can be any text in quotation marks. You can use single or double quotation marks:

Example

Varcarname= "VolvoXC60"

Varcarname='VolvoXC60'

You can use quotation marks in a string, as long as they do not match the quotation marks that surround the string:

Example

Varanswer= "It'salright"

Varanswer= "Heiscalled'Johnny'"

Varanswer='Heiscalled "Johnny"'

You will learn more about strings in the advanced parts of this tutorial.

JavaScript digit

JavaScript has only one numeric type. Numbers can be decimal or not:

Example

Varx1=34.00;// uses decimal point to write

Varx2=34;// does not use decimal points to write

Very large or very small numbers can be written by scientific (exponential) counting:

Example

Vary=123e5;//12300000

Varz=123e-5;//0.00123
