Finding and comparing a specific portion of a text in JavaScript: A guide

Question

Finding and comparing a specific portion of a text in JavaScript: A guide

Can you help me with a JavaScript algorithm that can find a substring within a string?

subStringFinder('abbcdabbbbbck', 'ab')

This should return index 0.

Similarly,

subStringFinder('abbcdabbbbbck', 'bck')

should return index 10.

Would you be able to provide guidance on writing this code?

--UPDATE:

With the help of @Jonathan.Brink, I was able to write code that successfully achieved this:

function subStringFinder(str, subString) {
  return str.indexOf(subString);
}

subStringFinder('abbcdabbbbbck', 'bck') // -> 10

Answer №1

If you're searching for the indexOf function, look no further. This handy function is readily available for use with the built-in string type, as well as with arrays.

For example:

var str = "abbcdabbbbbck";
var n = str.indexOf("bck");
// n is 9

Instead of creating a custom subStringFinder function, consider using the built-in indexOf for a more efficient solution.
