Convert the given string to a valid JavaScript identifier.
Different inputs will always generate unique identifiers.
- Code Generation: Automate safe variable naming in scripts, avoiding syntax errors from invalid characters.
- Compilers/Transpilers: Essential for non-JavaScript languages compiling to JavaScript, ensuring that identifiers are compliant.
- Dynamic Function Names: Generate unique and valid function names from dynamic content such as user inputs or database fields.
- API Wrappers: Convert API response properties into valid JavaScript object keys for easier access.
- Template Processing: Ensure template placeholders are converted to valid JavaScript identifiers when replaced with dynamic values.
