Estoy trabajando en una serie de objetos de libros y la tarea es consolar. Registrar una lista de todos los libros que contienen "empresas" o "personas" en su título.
const books = [{ title: 'How to win friends and influence people', authors: ['Dale Carnegie'], publisher: 'Pocket Books', year: '1936' }, { title: 'Management: tasks, responsibilities, practices', authors: ['Peter F. Drucker'], publisher: 'Harper Business', year: '1985' }, { title: 'Strength finder 2.0', authors: ['Tom Rath'], publisher: 'Gallup Press', year: '2007' }, { title: 'In search of excellence: Lessons from America\'s best-run companies', authors: ['Thomas Peters', ' Robert H. Waterman'], publisher: 'Harper Collins', year: '1982' }, { title: 'Built to last: Successful habits of visionary companies', authors: ['James C. Collins', 'Jerry I. Porras'], publisher: 'Harper Collins', year: '1994' }, { title: 'Reengineering the corporation: A manifesto for business revolution', authors: ['Michael Hammer', 'James A. Champy'], publisher: 'Harper Collins', year: '1993' }, { title: 'Competitive advantage: Creating and sustaining superior performance', authors: ['Michael E. Porter'], publisher: 'Free Press', year: '1998' }, { title: 'Crossing the chasm: Marketing and selling technology products to mainstream customers', authors: ['Geoffrey A. Moore', 'Regis McKenna'], publisher: 'Pocket Books', year: '1936' }, { title: '7 habits of highly effective people: Powerful lessons in personal change', authors: ['Stephen R. Covey'], publisher: 'Simon and Shuster', year: '1990' }, { title: 'The Six Sigma Way', authors: ['Peter S. Pande et al', 'Robert P. Neuman', 'Roland R. Cavanagh'], publisher: 'McGraw Hill', year: '2000' }, { title: 'The innovator\'s dilemma: When new technologies cause great firms to fail', authors: ['Clayton M. Christensen'], publisher: 'Harvard Business School Press', year: '1997' }, { title: 'The Essential Drucker', authors: ['Peter F. Drucker'], publisher: 'Harper Business', year: '2001' }]; Hasta ahora he intentado usar filter() e includes() como se indica a continuación, pero solo devuelve libros que contienen la palabra clave "personas".
let palabraclave = libros.filtro (títulolibro => títulolibro.título.includes('personas'||'empresas'));
consola.log(palabra clave);
Sugeriría usar Array.filter() junto con Array.some() para que coincida con el resultado deseado.
Creamos una matriz de palabras clave y luego devolvemos cualquier elemento que coincida con some de ellas.

Entonces puedes escribir la lógica afuera.
books.filter(book => book.title.includes('companies') || book.title.includes('people'))Si la coincidencia debe ser insensible a mayúsculas y minúsculas:
books.filter(book => { const titleLower = book.title.toLowerCase() return titleLower.includes('companies') || titleLower.includes('people') })puedes usar expresiones regulares:
const peopleRegex = /people/i const companiesRegex = /companies/i const result = books.filter(item=>peopleRegex.test(item.title) || companiesRegex.test(item.title))
