Extract a string from another string between two specific characters

I have a result string like below

*WTY:   this is Amy's home .
%mor:   pro:dem|this cop|be&3s n:prop|Amy's n|home .
%snd:   <00:00:00><00:01:23>
%WTY:   this is Amy’s home . errfr ::: |
*WTY:   last Sunday the television was showing the news report .
%mor:   adj|last n:prop|Sunday det|the n|television aux|be&PAST v|showing det|the n|news n|report .
%snd:   <00:01:77><00:06:65>
*WTY:   the dog come back again and play with Amy .
%mor:   det|the n|dog v|come adv|back adv|again conj|and v|play prep|with n:prop|Amy .
%snd:   <01:06:70><01:12:85>
%WTY:   {and} * (1.38) and_pfp (0.56) the dog (0.40) come back again err_m_s ::: and play with (0.56) Amy . err_m_s ::: |

I want to extact the words between first instance "*"(asterik) and ":"(semicolon) like here the result should b "WTY". I have tried doing below but it is not working as expected.

var ID=result.split('*').pop().split(':').shift();

Can anyone please point out the mistake or any other better solution?

If you are sure that your string contains these symbols, in terms of your functions you can write something like this:

result.split('*')[1].split(':')[0]

Use a regex 

var string = `*WTY:   this is Amy's home .
%mor:   pro:dem|this cop|be&3s n:prop|Amy's n|home .
%snd:   <00:00:00><00:01:23>
%WTY:   this is Amy’s home . errfr ::: |
*WTY:   last Sunday the television was showing the news report .
%mor:   adj|last n:prop|Sunday det|the n|television aux|be&PAST v|showing det|the n|news n|report .
%snd:   <00:01:77><00:06:65>
*WTY:   the dog come back again and play with Amy .
%mor:   det|the n|dog v|come adv|back adv|again conj|and v|play prep|with n:prop|Amy .
%snd:   <01:06:70><01:12:85>
%WTY:   {and} * (1.38) and_pfp (0.56) the dog (0.40) come back again err_m_s ::: and play with (0.56) Amy . err_m_s ::: |`;

var match = string.match(/\*(\w+):/g);
console.log(match);
