Convert Fraction String to Decimal?

Question

I\'m trying to create a javascript function that can take a fraction input string such as \'3/2\' and convert it to decimal—either as a string \'1.5\'

Answer 1

safer eval() according to MDN

const safeEval = (str) => {
   return Function('"use strict";return (' + str + ")")();
}

safeEval("1 1/2") // 1.5
