Converts a string to PascalCase format.

Signature

function toPascalCase(str: string): string

Description

The toPascalCase function converts a string to PascalCase format. It removes spaces, hyphens, underscores, and other separators, and transforms the string into a format where each word starts with a capital letter, with no spaces or separators between them.

Parameters

str: The string to convert to PascalCase.

Return value

A new string in PascalCase format.

Examples

Basic usage

// Converting different formats to PascalCase
const space = String.toPascalCase("hello world");
print(space); // Outputs: "HelloWorld"

const kebab = String.toPascalCase("hello-world");
print(kebab); // Outputs: "HelloWorld"

const snake = String.toPascalCase("hello_world");
print(snake); // Outputs: "HelloWorld"

const camel = String.toPascalCase("helloWorld");
print(camel); // Outputs: "HelloWorld"

Multiple words

// Converting multi-word strings
const multiple = String.toPascalCase("hello beautiful world");
print(multiple); // Outputs: "HelloBeautifulWorld"

const mixedSeparators = String.toPascalCase("hello_beautiful-world");
print(mixedSeparators); // Outputs: "HelloBeautifulWorld"

Handling edge cases

// Empty string
const empty = String.toPascalCase("");
print(empty); // Outputs: ""

// Single word lowercase
const single = String.toPascalCase("hello");
print(single); // Outputs: "Hello"

// Single word uppercase
const uppercase = String.toPascalCase("HELLO");
print(uppercase); // Outputs: "HELLO"

// Already in PascalCase
const alreadyPascal = String.toPascalCase("HelloWorld");
print(alreadyPascal); // Outputs: "HelloWorld"

Converting from other cases

// From sentence case
const sentence = String.toPascalCase("This is a sentence");
print(sentence); // Outputs: "ThisIsASentence"

// From title case
const title = String.toPascalCase("This Is A Title");
print(title); // Outputs: "ThisIsATitle"

// From snake_case
const snake = String.toPascalCase("user_first_name");
print(snake); // Outputs: "UserFirstName"

// From kebab-case
const kebab = String.toPascalCase("api-response-code");
print(kebab); // Outputs: "ApiResponseCode"

// From camelCase
const camel = String.toPascalCase("userLoginRequest");
print(camel); // Outputs: "UserLoginRequest"

Practical applications

// Convert strings to class names
function createClassName(name: string): string {
  return String.toPascalCase(name);
}

print(createClassName("user model")); // Outputs: "UserModel"
print(createClassName("api_response")); // Outputs: "ApiResponse"

// Convert event names to handler names
function createEventHandlerName(eventName: string): string {
  return `handle${String.toPascalCase(eventName)}`;
}

print(createEventHandlerName("button-click")); // Outputs: "handleButtonClick"
print(createEventHandlerName("form_submit")); // Outputs: "handleFormSubmit"
