console.log(Ansi.red('Hello World'));

• ...btw you can do it.

import { extends_proto } from '@nutsloop/ivy-ansi';
// after the imports run the extends_proto() function
entends_proto();

console.log( 'Hello World'.red() );

• ...btw you can redo it.

import { extends_proto, un_extends_proto } from '@nutsloop/ivy-ansi';
// after the imports run the extends_proto() function
entends_proto();

console.log( 'Hello World'.red() );

// after run extends_proto() function no more extends the String class.
un_extends_proto();

// it will throw TypeError
console.log( 'Hello World'.red() );

• using color256 method for 256 color. [0-255].

import { extends_proto } from '@nutsloop/ivy-ansi';
extends_proto();

console.log('Hello World'.color256(155));
console.log( 'Hello World'.bg_color256(155) );
