String Regex Methods

String regex methods use regular-expression patterns.

Invalid regex patterns raise a runtime error.

Checks whether the pattern matches the string.

Returns: boolean-style number.

Example:

'abc123'.match('[0-9]+');   // true
'abc'.match('[0-9]+');      // false

Returns the first text matched by the pattern.

Returns: string. If there is no match, returns an empty string.

Example:

'abc123def'.find('[0-9]+'); // '123'

Replaces all regex matches with replacement text.

Returns: string.

Example:

'abc123def'.replace('[0-9]+', '');     // 'abcdef'
