New to JS and VUE.
I have a variable numberOfItems in my data which has 10 as its value.
I need to compare if this value is equal to the sum of 5 different variables data
var numberOfItems = 10
var destinations = (this.campaign.shipments_ue + this.campaign.shipments_uk + this.campaign.shipments_islas + this.campaign.shipments_peninsula + this.campaign.shipments_international)
I get 22222 in destinations value instead of 10, what method should I use to sum them up so I can compare them?
Thanks!
Observation : Looks like you are adding a string instead of number.
If data type is string then it is resulting of concatenating strings not a number.
For Ex :
var num1 = '10', num2 = '20';
console.log(num1 + num2); // 1020 (Here both the variables are string)
num1 = 10;
console.log(num1 + num2); // 1020 (Here variable 1 is number but variable 2 is a string)
num2 = 20;
console.log(num1 + num2); // 30 (Here both the variables are number)Now, As per your requirement. You can use parseInt() function which helps in parsing a string argument and returns an integer.
Demo :
var num1 = '10', num2 = '20';
console.log(parseInt(num1) + parseInt(num2));
