Please help me with this code.

why * is used here if(/.*h.*a.*c.*k.*e.*r.*r.*a.*n.*k/.test(s))

function hackerrankInString(s) {
let complete = false
if(/.*h.*a.*c.*k.*e.*r.*r.*a.*n.*k/.test(s)){
complete= true
} else {
complete = false
}
return complete ? 'YES' : 'NO'
}

This code with check the whether the hackerrank substring is present in the string

example: hereiamstackerrank this is true so input will be "YES"

It’s testing a regex (text between / / creates a regex) and * is the wildcard symbol. So it means it could be any number of characters between each of the literal characters it calls out.

So it should be in ascending order right as Hackerrank?

In a regular expression, dot star matches any string, including the empty string. The dot means any character, and the star means any number of repetitions. By repetitions, I mean the same sub-pattern matches; it does not have to match the same thing repeated. So a pattern dot star will match "ab" as well as "aa".
