Is there a way to split a string into equal chunks of characters in JavaScript?

Question

Is there a way to split a string into equal chunks of characters in JavaScript?

What is the process for splitting a string into segments every X number of characters? To put it in perspective, if I have an extremely lengthy string and want to divide it into parts of 1000 characters each, how can this be achieved when the content varies every time?

var string = <my text string containing thousands of characters>

Answer №1

If you're looking to split a string into chunks, consider using Regular Expressions (Regex):

'examplestring'.match(/.{3}|.{1,2}/g); // 'exa', 'mpl', etc.

You can easily customize the chunk size by replacing 3 with your desired length.

Here's an example implementation: http://jsfiddle.net/ReRPz/1/

As a reusable function:

function splitIntoChunks(str, len) {
    var regex = new RegExp('.{' + len + '}|.{1,' + Number(len-1) + '}', 'g');
    return str.match(regex );
}

The RegExp creation overhead is minimal if you consistently split into chunks of the same length like 1000.

Here is a helpful function for splitting a string into parts:

function splitStringIntoParts(inputString, chunkLength)
{
    var result = [];
    while (inputString.length) {
        result.push(inputString.substring(0, chunkLength));
        inputString = inputString.substring(chunkLength);
    }
    return result;
}

var sampleString = "abcde12345fghij67890";
console.log(splitStringIntoParts(sampleString, 5));

This function can be used to divide a given string into equal parts of the specified length.

If you're looking to achieve this recursively, consider the following approach:

var input = "a lengthy text that spans multiple lines and contains an abundance of characters";

var outputArray = [];

function divideText( str, length ) {

    if( str.length < length )
        return outputArray.push(str);
    else
        outputArray.push(str.substring(0,length))

    divideText( str.substring(length), length );
}

divideText( input, 7 );

for( var j = 0; j < outputArray.length; j++ ) {
    document.write( outputArray[j] + "<br/>");  
}

/* Result:

To efficiently handle long strings, I would implement a function that breaks down the string into smaller chunks using the substring method.

     let str = //the given string
     let arr = [];

     for(let i=0; i<str.length; i+=1000)
     {
        let start = i;
        let end = (str.length - i) > 1000 ? (i+1000) : (str.length - i); 
        arr.push(str.substring(start, end));
     }

Here's an example:

let myLongString = "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.";
let currentSubstring = "";
let brokenSubstrings = [];

for(let i = 0; i < myLongString.length; i++) {
    currentSubstring += myLongString.charAt(i);

    if(i % 20 == 0) {
        brokenSubstrings.push(currentSubstring);
        currentSubstring = "";
    }

    if(i + 1 == myLongString.length) brokenSubstrings.push(currentSubstring);
}

Note: This code is provided as a guide and may require testing and adjustments.

You can then send the array and reconstruct it on the receiving end. To put it back together, you could use the following code:

let reconstructedString = "";
for(let i = 0; i < brokenSubstrings.length; i++) {
    reconstructedString += brokenSubstrings[i];
}

Adopting Joe Tuskan's concept:

let message = 'testing123testing123';
let length = 4;
let pattern = new RegExp(".{"+length+"}", "g");
let remaining = message.length - (message.length % length);

let sections = message.match(pattern);
sections.push(message.substring(remaining));

document.write(sections.join('<br>'));
