I want to use JavaScript to divide a string into three parts, regardless of the string's length. Each part can have a different number of characters.
For instance:
AABC:
AABBC
aheuc
hello world
Here is a function that can help you achieve your desired output:
function divideStringIntoThreeEqualParts(string) {
if (string.length <= 3) return string.split('');
const remainder = string.length % 3;
const divisor = Math.floor(string.length / 3);
const separator1 = remainder === 2 || remainder === 1 ? 1 : 0;
const separator2 = remainder === 1 || remainder === 0 ? 0 : 1;
const part1 = string.slice(0, divisor + separator1);
const part2 = string.slice(divisor + separator1, (divisor * 2) + separator1 + separator2);
const part3 = string.slice((divisor * 2) + separator1 + separator2);
return [part1, part2, part3];
}If you're looking to easily divide a string into three parts, the following method will do just that.*
function splitIntoChunks(string) {
var regex = RegExp(".{1,"+Math.ceil(string.length/3)+"}", 'g');
return string.match(regex);
}
This code creates a regular expression function specifically designed to break down a string into chunks. The uniqueness here lies in determining chunk length based on dividing the overall string length by 3 (as indicated in the regex variable).
* However, it's important to note that this method works best for strings longer than 5 characters. Shorter strings may not be evenly divided into 3 chunks due to insufficient length.
Sample outputs include:
> splitIntoChunks("abcdefg");
(3) ["abc", "def", "g"]
> splitIntoChunks("abcdefghijk");
(3) ["abcd", "efgh", "ijk"]
> splitIntoChunks("abc");
(3) ["a", "b", "c"]
> splitIntoChunks("abcd"); // :(
(2) ["ab", "cd"]
