Answer 1

You can use a regular expression to group your numbers.

const rx = /(\d{2})(\d{3})(\d{3}?)/

This would be 2 digits, 3 digits, and optional 3 digits.

const m = rx.exec('12345678')
if (m) {
  let parsed = m[1] + '.' + m[2]
  if (m[3]) {
    parsed += '.' + m[3]
  }
}

Answer 2

 var a = 531123121 var myStr = a.toString().split("") var myIndex = 0; for(let i in a.toString().split("")){ var revIndex = a.toString().length - (parseInt(i)+1); if((myIndex)==2 && revIndex.=0 && revIndex.=a.toString(),length-1){ myStr,splice(revIndex.0.".") myIndex = 0 }else myIndex+=1 } console.log(myStr.join(""))

Answer 3

You can do this very simply using the Intl API , and formatting the number to Spanish (es-ES).

Note: the language has come a long way since 2010 which is where of most of those answers in the duplicate come from.

 const number = 12051852; const number2 = 88312; const number3 = 9; const number4 = 12345678910; const out = Intl.NumberFormat('es-ES').format(number); const out2 = Intl.NumberFormat('es-ES').format(number2); const out3 = Intl.NumberFormat('es-ES').format(number3); const out4 = Intl.NumberFormat('es-ES').format(number4); console.log(out); console.log(out2); console.log(out3); console.log(out4);
