I am creating a team in JS to count the time the user will take to complete the task. I am using setInterval() to run the team but I am not able to increment to more than (1) the value of min() . This is my code:

const time = {
    min: 0,
    sec: 0,
    getSec: function(){
        this.sec++;
        if (this.sec === 59) {
            this.min=+1;
            this.sec =0;
        }else {
                if (this.sec >= 59) {
                this.sec = '00';
                this.min=+1;
            }
        }
    },
}

$sT = $('.score-panel').find('#time');
function setTime () {

    setInterval(function(){
      time.getSec();

    $sT.html(time.min + ':' + time.sec);
    },1000)
}
window.clearInterval(setTime());

if within else was an attempt to increment the minutes as the second gives 59. The window.clearInterval() is to stop the time when the user changes screen.

The problem is the assignment you are making. In this.min =+ 1 you are assigning the positive value of 1, so it always results in 1.

The sign of =+ is used to assign the unary + of a value to another:

a =+ b
a = + (b)

When using += you are using an assignment operator, which will add one more to the value you have:

a += b
a = a + b

You can see the resulting difference in values below:

num = 10;
num2 = -5;
num =+ num2;
console.log("Operação com '=+' retorna " + num);

num = 10;
num2 = -5;
num += num2;
console.log("Operação com '+=' retorna " + num);
