Comparing a number to the sum of numbers in JavaScript using VUE

Newbie in the world of JavaScript and VUE.

In my data, I have a variable called numberOfItems with a value of 10.

I am trying to check if this value is equal to the total sum of 5 different variables.

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)

Instead of getting 10, I'm receiving 22222 as the value for destinations. Can anyone suggest a method to correctly add them up for comparison?

Appreciate any help!

Notice : It appears that you are trying to add a string instead of a number.

If the data type is a string, then it will result in concatenating strings rather than adding numbers.

For Example :

var num1 = '10', num2 = '20';
console.log(num1 + num2); // 1020 (In this case, both variables are strings)

num1 = 10;
console.log(num1 + num2); // 1020 (Here, variable 1 is a number but variable 2 is a string)

num2 = 20;
console.log(num1 + num2); // 30 (In this scenario, both variables are numbers)

Now, for your specific needs, you can utilize the parseInt() function to convert a string argument into an integer value.

Example :

var num1 = '10', num2 = '20';

console.log(parseInt(num1) + parseInt(num2));
