📦 Kotipalli Phaneendra Kumar – String Helpers

A lightweight, safe, and predictable string utility library that provides common string operations with strict validation, consistent return values, and clean JSDoc documentation.

Designed for browser and JavaScript environments, these helpers handle invalid inputs gracefully by returning undefined instead of throwing errors.

✨ Highlights

• String length utilities
• Uppercase & lowercase helpers
• Trim / remove spaces
• Replace & replace-all helpers
• String concatenation
• Repeat & split utilities
• Case-insensitive word checks
• Fully documented with JSDoc
• Predictable return values

📦 Installation

npm install phane-tech-string-utils

🚀 Import

import {
  checkStringLength,
  changeToUpperCase,
  changeToLowerCase,
  removeSpaces,

  replaceAllWords,

  repeatTheWord,

  checkTheWord
} from "phane-js-string-helpers";

📚 Usage Examples

replaceAllWords("are are", "are", "is"); // "is is"
concateTwoWords("Phane", "Kumar"); // "Phane Kumar"
