What Data Type Is a String?
A string is a data type in programming that represents a sequence of characters. In HTML, strings are often used to display text or store user inputs.
String Basics
In HTML, strings are enclosed in quotation marks. There are two types of quotation marks that can be used: single quotes (”) and double quotes (“”). Both types are acceptable, but it’s important to be consistent in your usage.
For example:
<p>'Hello World!'
<p>"Hello World!"
String Manipulation
Strings can be manipulated using various built-in functions and methods. Some common operations include:
Concatenation
The process of combining two or more strings together is called concatenation. In HTML, concatenation can be achieved using the +
operator.
Example:
<p>'Hello ' + 'World!'
<p>"Hello " + "World!"
Length
To determine the length of a string, you can use the .length
property.
Example:
<p>'Hello World!'.length
<p>"Hello World!".length
Accessing Characters
You can access individual characters within a string by using square brackets and the index of the character you want to access. In HTML, indexing starts at 0.
Example:
<p>'Hello World!'[0]
<p>"Hello World!"[6]
Substring
To extract a portion of a string, you can use the .substring()
method.substring(0, 5)
<p>"Hello World!".substring(6)
