Array values to a string in loop

Question

I have an object (key value pair) looks like this

I want to get a string of '[100000025]/[100000013]'

I can't use var str = OBJ[0].PC + OBJ[1].PC (which gives me '100000025100000013') because I need the bracket structure. The number of items can vary.

Added >> Can it be done without using arrow function?

Answer 1

 const string = array.map(({PC}) => `[${PC}]`).join('/')

You could map every string to the string wrapped in brackets, then join that by slashes.
