No, it's a biwise XOR
Bitwise, sorry
10 ** 1 would be power, ** is the exponentiation operator, not ^

@mhesham32
Math.pow is the correct one
Dan Couper
@DanCouper
It's not infix though, that's what ** is for, it's a direct translation of your first example, and can be used same as *, +,-, /, or %. Like i = 2; i **= 4;

Hi. Could anyone tell me how to do array.join('<br>') inside angular js controller? Since angular ingores html tags in this example, and I really need this, how could I do it?

hello guys I have a problem here idk why num!==number.value didn't override the if conditon? help please
function convertToRoman(num) {
    var numArr = (num + '').split ``.map(x => x / 1);
    console.log(numArr);
    var numericalValueArr = numArr.map((number, index, array) => {
        if (array.length == 1) {
            return number;
        }

        var slicedArr = array.slice(index, array.length - 1).length;

        var tenToThePowerOfX = Math.pow(10, slicedArr);

        return number * tenToThePowerOfX;
    });
    console.log(numericalValueArr);

    var romanNumerals = [{
            value: 1,
            symbol: "I"
        },
        {
            value: 5,
            symbol: "V"
        },
        {
            value: 10,

        },

            symbol: "M"
        }
    ];


    function converter() {
        var numericalValue = numericalValueArr.map((num) => {

                if (num == 0) return null;


                if (num!==number.value&&num / number.value == 2) {//this is the problem
                    return number.symbol + number.symbol;
                }

                if (num!==number.value&&num / number.value == 3) {//this is the problem
                    return number.symbol + number.symbol + number.symbol;
                }


                for (let anotherNumber of romanNumerals) {
                    var subtract = num == number.value - anotherNumber.value;
                    //var adding=num==number.value+anotherNumber.value;

                    var remains = num - number.value;

                    }

morning everyone

HIya' Lee
Anyone have a minute?
Lee
@LeeConnelly12
Sure what's up
I'm trying to understand why my JS keeps saying there's an Unexpected end of input
There's a list of images, they're enclosed in {} with a ; to finish.
why is it Unexpected?

@Quantomistro3178 that was a fun part
how do you think you'll do it?
Quantomistro3178
@Quantomistro3178
I downloaded notepad++ to work on there cause the internet is bad here. but when I copied my code from codepen onto the text editor, the result wasnt the same when i ran it
the background-color of the body was messed up, and the cdn font links weren't working either....
@MWBauer I'm just thinking of a simple fixed bottom navbar. Last time I tried to add a navbar, I messed things up so wrong I almost scrapped the whole project.
Quantomistro3178
@Quantomistro3178
say, does anyone know how I could increase the rows in my "Message" input?
ronald
@ronstarcool
use text area?
Quantomistro3178
@Quantomistro3178
@ronstarcool how?
Quantomistro3178
@Quantomistro3178
like, how do i use it to increase the number of rows?
Marc
@MWBauer
I ended up with a floating navbar.
