Sort results By indexOf() of the input

[omerbarda130]

Im trying to understand how can i sort the options by the index of the input the user typed
for example:
the all options are: Thai, Sanskrit, Italian
and the user typed: "it"
the result should be: Italian, Sanskrit
because the indexOf "it" in Italian is lower then the indexOf "it" in Sanskrit.
the Thai does not contains "it" at all so he will disappear

result.sort((a,b)=>{a.indexOf(input)-b.indexOf(input)})
