Separate Fraction accordingly using javascript

Question

I can I separate fractions accordingly as numerator and denominator using javascript split.

var str="1/2+2/4";    
str.split('/').split('+');//not Working

Now I want it like num=[1,2] and den=[2,4]

Answer 1

You're trying to split an array.

An alternative is splitting the string by symbol + and then execute the function reduce .

 var str="1/2+2/4+3/4"; var result = str.split('+').reduce((a, c) => { var [num, den] = c.split("/"); a.den.push(den); a.num.push(num); return a; }, {num: [], den: []}); console.log(result); 

 .as-console-wrapper { max-height: 100% !important; top: 0; }
