Get a Substring by Char Index and Length

Demonstrates how to use the GetRange method to get a substring by index and length.

Note: This example demonstrates the GetRange method which was added in Chilkat v9.5.0.87.

React Native

import { StringBuilder } from '@chilkat/react-native'

function chilkatExample() {
  const sb = new StringBuilder();

  // Load a file that contains this string:  0123456789ABCDEF
  sb.loadFile('qa_data/txt/remove_chars.txt', 'utf-8');

  // Return "56789A" from the string.
  // if removeFlag is true, the returned string is also removed from the sb.
  const removeFlag = true;
  const result = sb.getRange(5, 6, removeFlag);

  console.log(result);
  console.log(sb.getAsString());

  // Output is: 
  // 
  // 56789A
  // 01234BCDEF
}
