Converts a string to start case.

const startCased = startCase(str);

Usage

startCase(str)

Use startCase when you want to convert a string to Start Case. Start Case is a naming convention where the first letter of each word is capitalized and separated by spaces.

import { startCase } from 'es-toolkit/compat';

// Convert regular string
startCase('hello world');
// Returns: 'Hello World'

// Keep words that are already uppercase
startCase('HELLO WORLD');
// Returns: 'HELLO WORLD'

// Convert hyphen-separated string
startCase('hello-world');
// Returns: 'Hello World'

// Convert underscore-separated string
startCase('hello_world');
// Returns: 'Hello World'

null or undefined are treated as empty strings.

import { startCase } from 'es-toolkit/compat';

startCase(null); // ''
startCase(undefined); // ''

Parameters

• str (string, optional): The string to convert to start case.

Returns

(string): Returns the start case converted string.
