Ways to separate a string based on changing values in Javascript

Given this unmodifiable string:

"AAACCDEEB"

I am looking to split it into an array whenever the value changes. In this scenario, I would end up with 5 arrays like so:

[['A','A','A'], ['C','C'], ['D'],['E','E'], ['B']]

Answer №1

you might want to give this a shot

"AAACCDEEB".match(/(.)\1*/g) 

You'll get results like ["AAA", "CC", "D", "EE", "B"]

This code uses a regular expression pattern to match any character repeated 0 or more times, making it quite versatile.

If you're interested in learning more about regular expressions, there are plenty of resources available - they can be very handy in situations like these!

If my solution works for you, feel free to accept it as the answer :)

Answer №2

Perhaps a different approach would look something like this:

 var str = "AAACCDEEB";
 var strArray = [[], [], [], [], []];
for(var x = 0; x <= (str.length-1); x++){
var val1 = 'A';
var val2 = 'C';
var val3 = 'D';
var val4 = 'E'
var val5 = 'B';
for(var n = 0; str[x] == val1; n++){
strArray[0][n] = str[x];
}
for(var m = 0; str[x] == val2; m++){
strArray[1][m] = str[x];
}
for(var o = 0; str[x] == val3; o++){
strArray[2][o] = str[x];
}
for(var z = 0; str[x] == val4; z++){
strArray[3][z] = str[x];
}
for(var i = 0; str[x] == val5; i++){
strArray[4][i] = str[x];
}

}
document.write(strArray);
