Why is parseInt displaying Nan? – Angular

I am currently iterating through an array and adding the key to my panels array. I am getting the correct length of the array which is three but my parseint is displaying NaN. How can I convert the key which is a string to an int to display panel-0 for example instead of panel-NaN.

Object.keys(this.Category).forEach((key) => {
      this.panels.push(parseInt(key, 3));
      this.activeIds = this.panels.map(p => 'panel-' + p);
    });```

>Solution :

what you are doing is parseInt('Car' 3), since "Car" is not a number you will get NaN

probaby you want something like this:

Object.keys(this.Category).forEach((key) => {
   this.panels.push('panel-' + panels.length + 1);
});
