How to get values related to every loc inside location objec

Question

I work on angular 7 

I need to loop over location and get all loc values from locations array 

Locations":
[{"Loc":2937,"Fab":"Assembly"},
{"Loc":27746,"Fab":"FAB"},{"Loc":27751,"Fab":"Assembly"},
{"Loc":2931,"Fab":"Assembly"},{"Loc":27801,"Fab":"FAB"},
{"Loc":27739,"Fab":"Assembly"},{"Loc":27775,"Fab":"FAB"},
{"Loc":27789,"Fab":"FAB"}]

Result i need to return is :

result returned
2937
27746
27739
27789

I need to store all values related to loc to array locations

2937

27746

27739

27789

to access first item

this.LocationId= this.data.Locations[0]['Loc'];

but what actually need store all values on array related to loc inside locations array?

How to do that please
