Python title method in JavaScript

· Thomas Taylor

What is the equivalent for the Python string title method in JavaScript? Python’s native str.title() method returns a string with title-casing— i.e. the first letter of each word is capitalized.

str.title() method in JavaScript

Unfortunately, JavaScript does not contain a standardized str.title() method; however, a function can be created that implements equivalent behavior.

In Python, here are a few examples of the str.title() method:

1print("WeIrD cAsInG".title()) # Weird Casing
2print("HELLO WORLD".title()) # Hello World
3print("nospaceHERE".title()) # Nospacehere
4print("there's a snake in my boot".title()) # There'S A Snake In My Boot

This is an equivalent JavaScript implementation:

1function title(str) {
2  return str.toLowerCase().split(' ').map(w => w.charAt(0).toUpperCase() + w.slice(1)).join(' ');
5console.log(title("WeIrD cAsInG")); // Weird Casing
6console.log(title("HELLO WORLD")); // Hello World
7console.log(title("nospaceHERE")); // Nospacehere
8console.log(title("there's a snake in my boot")); // There'S A Snake In My Boot
