Faced a similar type of query and worked for me.

My case:

article Id comes in the string format from route params and from API I get the data in number format.

If I check with !=, ES lint throws an error. So I am converting a string to number in vanilla javascript using Number() method.

const articleId = Number(this.route.snapshot.params['articleId']);

data.forEach((element, index) => {

    // console.log(typeof(element['id']), element['id']); 
    // 4, number
    // console.log(typeof(this.route.snapshot.params['articleId']), this.route.snapshot.params['articleId']);
    // 4, string (converted to number)

    if (element['id'] !== articleId) {
        //my implementation
     }
}
