const width = '190px';
const totalImages = 10;
const totalWidth = parseInt ( width * totalImages );

const totalWidth = parseInt(width) * totalImages;

this didn't go through...tho Could someone tell me why?

231,275 PointsType coercion (as invoked by he unary "+" trick) works when the string value only contains digits.
But the "px" in this string makes it only convertible with "parseInt".

there is not need of + & you forgot the capitalization of width "W"
