How to split value in javascript?

Question

Here I have one month object In this month object inside value 1,2,3,4,5 and selected experience value is 04 (see console) so want to find value and I compare both but I got undefined because 4 and 04 not matched How to match them ?

console.log(selectedExperience.from.split('/')[0])) // 04

console.log(months) // [ { value : 1, name: "one"}
                          { value: 2, name: "two" }
                          { value: 4, name: "four" } ]

console.log(months.find(month => month.value === selectedExperience.from.split('/')[0])); // undefined

Your best bet would be to use parseInt on your "04" string. Such as parseInt(selExp.from.split("/")[0], 10) which will yield the number 4 — Sean Kelly

The split method return a String and because of your comparison "===" with the value which is a INT, your find does not return anything — Maxime Girou

What about to convert it into an int?

console.log(months.find(month => month.value === parseInt(selectedExperience.from.split('/')[0])));

You can use parseInt

month.value === parseInt(selectedExperience.from.split('/')[0])

console.log(parseInt('04') === 4)

Use Number so you are comparing numbers not strings:

Number(month.value) === Number(selectedExperience.from.split('/')[0])

try to convert string to number with "+" operator:

var test = "04";
console.log(test); //04
console.log(+test); //4

console.log(months.find(month => month.value === +selectedExperience.from.split('/')[0]));

Assuming 04 is a string , do a parseInt or convert it to number before comparing or else use unary operator

console.log(selectedExperience.from.split('/')[0])) // 04
let exp = parseInt(selectedExperience.from.split('/')[0],10)

console.log(months)  // [ { value : 1, name: "one"}
                     //   { value: 2, name: "two" }
                     //   { value: 4, name: "four" }] 

console.log(months.find(month => month.value ===exp  ))

.split() will return you an array of strings. So for comparing with an integer, you need to parse it using parseInt.

var test = "04/12";
var months = [{
    value: 1,
    name: "one"
  },
  {
    value: 2,
    name: "two"
  },
  {
    value: 4,
    name: "four"
  }
];

console.log(test.split('/')[0]);
console.log(months);

console.log(months.find(month => month.value === parseInt(test.split('/')[0])));
