let Arra1 = ["1","2","3","4","5"]
let Arra2 = ["R","B"]
console.log(Arra1.map((num, ind)=>Arra2[ind%Arra2.length]))
//["R","B","R","B","R"]

You can write this :

r = []
let j = 0
for (let i=0; i<Arra1.length; i++)
{
    if (j>= Arra2.length)
        j = 0
    r.push(Arra2[j])
    j++
}

Hope it helps.
