What is string trimming?

Trimming removes whitespace (spaces, tabs, newlines) from the beginning and/or end of a string. You can trim both sides, left only, or right only.

What is string padding?

Padding adds characters to a string to reach a desired length. Left padding adds to the start, right padding adds to the end. Common uses include formatting numbers and aligning text.

What is string truncation?

Truncation shortens a string to a maximum length, typically adding an ellipsis (...) to indicate text was cut off. Useful for previews and limited display areas.

Slugify converts text into a URL-friendly format by lowercasing, replacing spaces with hyphens, and removing special characters. Example: "Hello World!" becomes "hello-world".

What is HTML escaping?

HTML escaping converts special characters like , &, and quotes into their HTML entity equivalents. This prevents XSS attacks and ensures text displays correctly in HTML.

What characters can I use for padding?

You can use any character for padding, though spaces and zeros are most common. For example, padding "42" to 5 characters with zeros gives "00042".

How does word wrap work?

Word wrap inserts line breaks to ensure no line exceeds a specified width. It breaks at word boundaries when possible to maintain readability.

Can I combine multiple operations?
