Trigger Rerender When Updating Array Using useEffect Hook

To update an array, best to spread the array into the new array.

const newBlogList = [
  { blogTitle: 'test one', url: 'http://www.testone.com' },
  { blogTitle: 'test two', url: 'http://www.testtwo.com' }
]
setBlogs(newBlogList) // option 1: does not trigger rerender
setBlogs([...newBlogList]) // option 2: triggers rerender

In option 1, react interpret the array as the same one.
