Signature

function toCamelCase(str: string): string

Description

Parameters

str: The string to convert to camelCase.

Return value

A new string in camelCase format.

Examples

Basic usage

// Converting different formats to camelCase
const space = String.toCamelCase("hello world");
print(space); // Outputs: "helloWorld"

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

const snake = String.toCamelCase("hello_world");
print(snake); // Outputs: "helloWorld"

const pascal = String.toCamelCase("HelloWorld");
print(pascal); // Outputs: "helloWorld"

Multiple words

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

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

Handling edge cases

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

// Single word uppercase, each next letter will be considered new word
const single = String.toCamelCase("HELLO");
print(single); // Outputs: "hELLO"

// Already in camelCase
const alreadyCamel = String.toCamelCase("helloWorld");
print(alreadyCamel); // Outputs: "helloWorld"

Converting from other cases

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

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

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

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

// From PascalCase
const pascal = String.toCamelCase("UserLoginRequest");
print(pascal); // Outputs: "userLoginRequest"
