javascript split string into groups code example

Example 1: javascript string into substrings of length

function chunkSubstr(str, size) {
  const numChunks = Math.ceil(str.length / size)
  const chunks = new Array(numChunks)

  for (let i = 0, o = 0; i < numChunks; ++i, o += size) {
    chunks[i] = str.substr(o, size)
  }

  return chunks
}

Example 2: javascript split by comma

<script>
var names = 'Harry,John,Clark,Peter,Rohn,Alice';
var nameArr = names.split(',');
console.log(nameArr);
 
// Accessing individual values
alert(nameArr[0]); // Outputs: Harry
alert(nameArr[1]); // Outputs: John
alert(nameArr[nameArr.length - 1]); // Outputs: Alice
 
var str = 'Hello World!';
var chars = str.split('');
console.log();
 
// Accessing individual values
alert(chars[0]); // Outputs: H
alert(chars[1]); // Outputs: e
alert(chars[chars.length - 1]); // Outputs: !
</script>
