JavaScript str.substring() Function
This function gets the characters from a string, between two specified indices, and returns the new string.
Syntax:
str.substring(start, end);
Example: This example uses the parameter (3, 7) for both functions and returns the output.
Javascript
const str1 = "w3wiki";const substrResult = str1.substr(3, 7);const substringResult = str1.substring(3, 7);console.log("Str.substr(3, 7) =", substrResult);console.log("Str.substring(3, 7) =", substringResult); |
Output
Str.substr(3, 7) = ksForGe Str.substring(3, 7) = ksFo
Difference between substr() and substring() in JavaScript
In JavaScript Both of the functions are used to get the specified part of the string, But there is a slight difference between them. substr() and substring() are string methods used to extract parts of a string. The main difference is that substr() accepts a length parameter, while substring() accepts start and end indices.
