in the second method of object called “inRange” in the last step inside this method i declare a variable called isInRange like this but the code don’t run right in the terminal :






// Do not write or modify code below this line.

const _ = {
  clamp(number, lower, upper) {
let lowerClampedValue = Math.max(number, lower)
let clampedValue = Math.min(lowerClampedValue, upper)
return clampedValue
},
inRange (number, start, end) {
  let aux = 0
  if(end == undefined) {
    end = start
  start = 0
  
}
if(start > end){
  aux = start
  start = end
  end = aux
}
let isInRange = number > start && number < end
return isInRange

}

}
console.log(_.clamp(4, 5, 6))
console.log(_.inRange(3, 7, 6))
module.exports = _;
#2

Remember to include the start value in the range.

#3

but the start value is include in the range

#4

But is it really included?

#5

  let aux = 0
  else if(end == undefined) {
    end = start
  start = 0
  
}
else if(start > end){
  aux = end
  start = aux
  end = start
}
let isInRange =  number => start && number <= end
return isInRange

},
words(str) {
return str.split('')
},
pad(string, length) {
  
}

}

console.log(_.inRange(3, 8, 6))
module.exports = _;

but when i try to run my code this message appear tome in the console :
$ node test/inRange.js
module.js:472
throw err;

#7

Is the end value intended to be in the range?

#8

I Had excluded the end value from the range but it the same thing happen also
“&& number < end” not “number <= end”

#9

From this error message it appears that the test-script can’t be located. You should be able to look in the test directory to see the names of the test-files. My test-file is called in-range.js for this project so try to start the test with:

node test/in-range.js
