Fertilize plants which names consist of only word characters

In the previous lessons we've wrote regular expressions where one token match exactly one symbol. Let's say we want to write an expression to match all the strings starting with "foo" and ending with "bar" with any two word characters in between. We would write something like this:

console.log(!!"foo42bar".match(/^foo\w\wbar$/)) // true 

But what if we don't know in advance how many word characters will be between "foo" and "bar"? What if there could be zero or any word characters in the middle? Our previous expression would fail there:

console.log(!!"foo4bar".match(/^foo\w\wbar$/)) // false 

console.log(!!"foo423bar".match(/^foo\w\wbar$/)) // false 

console.log(!!"foobar".match(/^foo\w\wbar$/)) // false 

This is where * would help us:

console.log(!!"foo42bar".match(/^foo\w*bar$/)) // true 

console.log(!!"foo4bar".match(/^foo\w*bar$/)) // true 

console.log(!!"foobar".match(/^foo\w*bar$/)) // true 

If you want to match "*" literally, escape it with backslash:

console.log(!!"*".match(/\*/)) // true
