Some popular checks that can be done with regular expressions are now possible in a more semantic way. Here are some functions that we can use:

Function Name	Syntax	Output
`startsWith`	`s1.startsWith(s2)`	true if and only if `s1` starts with `s2`
`endsWith`	`s1.endsWith(s2)`	true if and only if `s1` ends with `s2`
`includes`:	`s1.includes(s2)`	true if and only if `s2` is a substring of `s1`
`repeat`	`s.repeat(n)`	replicates `s` `n` times, and joins them
