Strings 5/5

Changing Cases of String Variables

In JavaScript, we can convert lower-case string values to upper-case and vice versa. To convert lower-case string to upper-case we use the method toUpperCase() while the method toLowerCase() is for converting string into lower-case. Let’s look at an example.

console.log('JavaScript'.toUpperCase()); console.log('JavaScript'.toLowerCase());
copy

  • We can use different kinds of special characters like \n is a special character used for entering a new line.
  • To get a character at a position we , use: [] or .charAt().
