Join

Concat
const testArray = [[1, 2, 3], [4, 5, 6], [7, 8, 9, 10, 11]] const newTestArray = [].concat(...testArray)
Reduce
const testArray = [[1, 2, 3], [4, 5, 6], [7, 8, 9, 10, 11]] const newTestArray = testArray.reduce((prev, next) => prev.concat(next))
Raw
const testArray = [[1, 2, 3], [4, 5, 6], [7, 8, 9, 10, 11]] var newTestArray = new Array(); for (var x = 0; x < testArray.length; x++){ for (var y = 0; y < testArray[x].length; y++){ newTestArray.push(testArray[x][y]) } }
