  • I’m sure it’s duplicate, but I haven’t found the question that already exists.

  • @hkotsubo I suggest you post this in an answer. :)

  • @I think the duplicate that Anderson found already solves the problem. And the documentation that Linkei says is an experimental feature that may not work well on all browsers, so I don’t think it’s even worth an answer...

you can do it this way.:

var matriz = [
  ['A', 'B', 'C'],
  ['D'],
  ['E', 'F'],
  ['G', 'H', 'I', 'J']
]

var array = matriz.reduce((list, sub) => list.concat(sub), [])
console.log(array)

var x = [["1", "2", "3"], ["3", "4", "5"]];    
var y = x[0].concat(x[1]);
