JavaScript entering IF Statement that's not true

Question

I am currently debugging a code I've not written and am generally not very experienced with JavaScript, but I am quite puzzled with this one. Why is the Script entering the second if Statement, when the condition is not true? :o

Code:

onChangeMinVotes(event) {
            console.clear()
            console.log("START");
            console.log("event.target.value: " + event.target.value);
            console.log("numberOfThemen: " + this.numberOfThemen);
            console.log("this.min_votes: " + this.min_votes);
            console.log("BEFORE UPDATE");
            this.update()
            console.log("AFTER UPDATE");
            console.log("event.target.value: " + event.target.value);
            console.log("numberOfThemen: " + this.numberOfThemen);
            console.log("this.min_votes: " + this.min_votes);
            console.log("BEFORE IF");
            if (event.target.value <= 0) {
                console.log("IF 1");
                this.min_votes = 1
            } else if (event.target.value > this.numberOfThemen) {
                console.log("IF 2");
                console.log("event.target.value: " + event.target.value);
                console.log("numberOfThemen: " + this.numberOfThemen);
                $('#myModal').modal("show")
                //this.min_votes = this.numberOfThemen
            } else if (event.target.value > 10) {
                console.log("IF 3");
                this.min_votes = 10
            }
            console.log("AFTER IF");
            console.log("event.target.value: " + event.target.value);
            console.log("numberOfThemen: " + this.numberOfThemen);
            console.log("this.min_votes: " + this.min_votes);
            console.log("END");
        },

Console Output:
