There is also a strong business case for accessibility. Accessibility stands in one line with other best practices such as mobile web design, device independence, multi-modal interaction, usability, design for older users, and search engine optimization (SEO). Case studies show that accessible websites have better search results, reduced maintenance costs, and increased audience reach, among other benefits.

}
While testing code:
examples:
Enzyme
const React = require('react')
const App = require('./app')
const { mount } = require('enzyme')
const { axe, toHaveNoViolations } = require('jest-axe')
expect.extend(toHaveNoViolations)
it('should demonstrate this matcher`s usage with enzyme', async () => {
const wrapper = mount(<App/>)
const results = await axe(container.getDOMNode())
expect(results).toHaveNoViolations()
})
React Testing Library
const React = require('react')
const App = require('./app')
const { render, cleanup } = require('@testing-library/react')
const { axe, toHaveNoViolations } = require('jest-axe')
expect.extend(toHaveNoViolations)
it('should demonstrate this matcher`s usage with react testing library', async () => {
const { container } = render(<App/>)
const results = await axe(container)
expect(results).toHaveNoViolations()
cleanup()
})
