javascript extend array
The .push method can take multiple arguments. You can use the spread operator to pass all the elements of the second array as arguments to .push:
>>> a.push(...b)
If your browser does not support ECMAScript 6, you can use .apply instead:
>>> a.push.apply(a, b)
Or perhaps, if you think it's clearer:
>>> Array.prototype.push.apply(a,b)javascript array extend
>>> a.push(...b)array javascript extend
var a = [1, 2, 3];
a = a.concat([5, 4, 3]);Copyright © 2021 Codeinu
