What is String Escaping?

String escaping is the process of converting special characters in a string to a format that can be safely used in a specific context, such as programming code, data files, or URLs. Escaping ensures that special characters are interpreted correctly and don't break the syntax or functionality of the code or data structure.

When to Use String Escaping

• When including strings in programming code (JavaScript, Python, etc.)
• When creating HTML or XML content dynamically
• When generating JSON data
• When constructing URLs with query parameters
• When working with CSV data containing quotes or commas
• When creating SQL queries with string parameters

Types of String Escaping

JavaScript String Escaping

JavaScript requires escaping of special characters such as quotes, newlines, and backslashes within strings. Common escape sequences include:

• \" - Double quote
• \' - Single quote
• \\ - Backslash
• \n - Newline
• \r - Carriage return
• \t - Tab
• \b - Backspace
• \f - Form feed
• \uXXXX - Unicode character

HTML Escaping

HTML escaping converts special characters to their HTML entity equivalents to prevent them from being interpreted as HTML markup. Common HTML entities include:

• < - Less than sign (<)
• > - Greater than sign (>)
• & - Ampersand (&)
• " - Double quote (\")
• ' - Apostrophe (')

URL Encoding

URL encoding replaces special characters in URLs with percent-encoded values. For example:

• %20 - Space
• %3F - Question mark (?)
• %26 - Ampersand (&)
• %3D - Equals sign (=)
• %25 - Percent sign (%)
