Improve resistor-color-duo: handle solutions based on reduce
Currently, when a solution contains reduce
, we explicitly bail out early. The following two examples should be considered approvable, but not optimal. Both should come with a hint.
const value = (colors) => {
return Number(
colors
.slice(0,2)
.reduce((digits, color) => digits + colorCode(color), '')
)
}
Use the type-juggling message hint.
function value(colors) {
return colors
.slice(0,2)
.reduce((value, color, index) => value + colorCode(color) * Math.pow(10, 1 - index), 0)
}
Use a new hint: Is reduce
really the best candidate when trying to get the sum of significant digit values, when there are two values only.
