Answer 2

function splitStrings(str, n) {
  	const arr = [];

  	for (let i = 0; i < str.length; i += n) {
    		arr.push(str.slice(i, i + n));
  	}

  	return arr;
}

const str = 'javascript c++ c typescript node.js';
const N = 4;

console.log(splitStrings(str, N));

  
  
  
  
/*
run:
  
["java", "scri", "pt c", "++ c", " typ", "escr", "ipt ", "node", ".js"]
  
*/
