Angular 4 : giving concatenated values instead of adding the values

Question

I am working in an angular 4 application ,In this I am trying to add 1 with the parameter value of a method .

Ex: if the method receives 1 as the parameter value I want to add parameter value + 1 inside the method .but it returns 11 instead of 2.

addCount(mCount){
   mCount += 1;
   console.log(mCount);
}

can anyone help me to solve this

of course mCount is a string then. mCount = parseInt(mCount) + 1; — Ashish Ranjan

You might be having your value as a string, just convert it into a number before adding. Use + operator to convert it into a number.

addCount(mCount){
   mCount = +mCount + 1;
   console.log(mCount);
}

use ParseInt to convert to a number, otherwise it will be considered as a string and concatenated,

mCount = parseInt(mCount) + 1
