Outstaffing provides a number of benefits for technology companies:
minimum time spent: you get a developer (or a whole team) with the required level of knowledge immediately, on the day of the call, and do not spend up to several weeks on independent searches and interviews;
there is no hassle associated with employment: an outsourced developer does not need to be registered as a full-time developer, allocate a workplace and equipment for him, keep accounts on it, pay vacations and sick days - you pay only for an hour of work (or for the finished result);
the ability to completely transfer the task to a specialist or a team, and get the finished result without wasting time on regular monitoring;
Outstaffing is especially useful for those who do not regularly work with VueJS, and who do not need to keep their specialist on staff all the time.
