Part-5 | 10 - Slicing and Extracting Parts of a String | Complete Course for Web Development |
In JavaScript, you can use the .slice() method to extract a part of a string and create a new string with the extracted characters. The slice() method takes two arguments: the start index and the end index of the characters you want to extract.
Here's an example of using the slice() method to extract the first 5 characters of a string:
The slice() method extracts the characters from the start index up to, but not including, the end index.
You can also use a negative number as an index. The index -1 refers to the last character, -2 refers to the second last character and so on
You can also use the .substring() method to achieve the same outcome, it's working in the same way as .slice().
If you want to extract a part of a string and replace it with something else, you can use the .splice() method. The splice() method takes three arguments: the starting index, the number of characters to remove, and the characters to insert in place of the removed characters.
