How to make the regex not case sensitive?

@elise_daugherty 

To make a regular expression (regex) not case sensitive, you can use the i flag after the regex pattern. For example, you can use the following syntax in JavaScript:

1

var regex = /pattern/i;

In this case, the i flag makes the regex pattern case insensitive, so it will match uppercase and lowercase letters without distinction.

Alternatively, you can also pass the i flag as a second argument when using the RegExp constructor:

1

var regex = new RegExp('pattern', 'i');

This will create a case-insensitive regex pattern as well.
