In this article I am going to write about converting a javascript variable to integer. Its important to have both variable as integer when you’re doing calculations using javascript. I’ll share 2 ways here in this article, there might be other ways as well. Please feel free to share your favourite way in comments section.
Ok, Let’s start with an example:
As you can see in the example, I have 2 variables where one is string and another one is integer. And in the 3rd variable, I am doing an addition of the first 2 variables. Now, If you run this code, it will output 99 instead of 18 !
But you need it to provide 18 as output. Let’s have a look at the ways to do that.
Way 1:
This is the simplest way for converting a javascript variable to integer. What you need to do is just put a + before the string variable. Just like the following:
This code will output 18 which is perfect! Now let’s have a look at the other way.
Way 2:
You can use parseInt() function to convert string variable to integer. Let’s see how:
It will also return 18!
Pretty simple, wasn’t it ? 😉
