How to split a string into chunks of two characters each using RegEx in TypeScript

Answer 1

function splitStringIntoChunksUsingRegex(str: string, chunkSize: number): string[] | null {
    // Match groups of `chunkSize` characters
    const regex: RegExp = new RegExp(`.{1,${chunkSize}}`, 'g');

    return str.match(regex); // Returns an array of strings or null
}

const str: string = "abcdefghijk";
const chunkSize: number = 2;
const chunks: string[] | null = splitStringIntoChunksUsingRegex(str, chunkSize);

if (chunks) {
    console.log("Chunks of two characters:");
    chunks.forEach((chunk: string) => console.log(chunk));
} else {
    console.log("No chunks found.");
}



   
/*
run:
    
"Chunks of two characters:" 
"ab" 
"cd" 
"ef" 
"gh" 
"ij" 
"k" 
       
*/
