Question

Create a pair of variables by utilizing the split function

I have a string that looks like this

test/something/else

My goal is to create two separate variables:

first = test
second = something/else

I attempted to achieve this using the following code snippet:

const [first, ...second] = "test/something/else".split("/");

While the above code successfully assigns the correct value to first, second ends up being an array. Do I need to concatenate the elements in this array to obtain the desired value?

Answer №1

To extract two specific strings from a given text, you can utilize a regular expression that matches a forward slash '/' followed by any characters:

const str = 'test/something/else';
const [, firstString, secondString] = str.match(/([^/]+)\/(.*)/);
console.log(firstString);
console.log(secondString);

If using the split method is necessary and you want to avoid an extra array, you can achieve a similar outcome by incorporating the second part into a capture group:

const str = 'test/something/else';
const [firstPart, secondPart] = str.split(/\/(.*)/);
console.log(firstPart);
console.log(secondPart);

Indeed, the most common way to accomplish this is by using the built-in method .split() followed by .join(‘’) on the tail elements.

An alternative approach that might be slightly faster involves checking for the index and then slicing the string accordingly, as demonstrated in the following code snippet:

function splitString(str, delimiter) {
  const index = str.indexOf(delimiter);
  const firstPart = str.slice(0, index);
  const secondPart = str.slice(index);
  return [firstPart, secondPart];
}

To solve this problem, we can use two variables. First, store a string that contains '/' in it. Second, use the split method with the expression /(.*)/ to separate the string at the forward slash and then display the results using console log.

var str = "how r u?/kkk/jj";
const [first, second] = str.split(/\/(.*)/);
console.log(first);
console.log(second);

Breaking down the string using the split method creates arrays. The string is divided after each '/' and when viewing the items through console log, the separated strings are displayed.
