The first function returns a number that we do not have in the array, the second one generates an array with 100 elements obtained with the function above, I hope it works for you.

    function getRnd(numberArr) {
        let newNumber;
        while (!newNumber || numberArr.includes(newNumber)) {
            newNumber = Math.floor((Math.random() * 100) + 1);
        }
        return newNumber;
    }


    function generateNumbers() {
        const numberArr = [];
        while (numberArr.length !== 100) {
            const n = getRnd(numberArr);
            numberArr.push(n);
        }
        return numberArr;
    }
    
    console.log(generateNumbers());
