How to remove padding from html element when pasted in js

there is a problem with inserting html into js , when inserting indents are added and I don’t understand why. Building a simple calculator

for (var i = 0; i < num.length; i++) {
    num[i].addEventListener("click", function () {
        if (!operator) {

            console.log(this)
            num1 += this.textContent
            ny.push(num1)
            console.log(ny)
            result.innerHTML = num1;
        } else if (operator.length > 0) {

            num2 += this.textContent
            result.innerHTML = num2;
        }


    })

}
