Split string into array of equal length strings

Question

I have a string that I need split into smaller strings with an equal length of 6. I tried using:

\'abcdefghijklmnopqrstuvwxyz\'.split(/(.{6})/)

Answer 1

Use match in conjunction with a global flag, instead of split. {1,6} is needed, to also include the last part of the matched string. Patterns are greedy by default, which means that as much is matched as possible. So, .{1,6} will only match less than 6 characters at the end of a string.

'abcdefghijklmnopqrstuvwxyz'.match(/.{1,6}/g);

Result:

["abcdef", "ghijkl", "mnopqr", "stuvwx", "yz"];

_{Note that the returned object is a true array. To verify:}

console.log('.'.match(/./g) instanceof Array);  //true
