I'm writing a program that removes vowels from str parameter and I've decided to use a switch statement to achieve this goal. I'm pretty bad at explaining stuff so I'll give you an example:
No offense but,\nYour writing is among the worst I've ever read
Should become
N ffns bt,\nYr wrtng s mng th wrst 'v vr rd
But my output looks like this:
N ffns bt,\nYur wrtng s mng th wrst 'v vr rad
The program decided to leave "u" and "a" for some reason. After nearly 1,5h of looking for a cause, I give up because I have literally no clue what I did wrong.
function disemvowel(str) {
let arr = str.split(''); // str -> arr
for (let x = 0; x <= arr.length; x++) { // remove vowels
switch(arr[x]) {
case "a":
case "e":
case "i":
case "o":
case "u":
case "A":
case "E":
case "I":
case "O":
case "U":
arr.splice(x, 1);
break;
}
}
str = arr.join([separator = '']) // arr -> str
return str;
}The array length is changing after every splice. You can define the length at first and decrement x every time you delete an item:
function disemvowel(str) {
let arr = str.split(''); // str -> arr
const length = arr.length;
for (let x = 0; x < length; x++) { // remove vowels
switch(arr[x]) {
case "a":
case "e":
case "i":
case "o":
case "u":
case "A":
case "E":
case "I":
case "O":
case "U":
arr.splice(x, 1);
x--;
break;
}
}
str = arr.join([separator = '']) // arr -> str
return str;
}
console.log(
disemvowel("No offense but,\nYour writing is among the worst I've ever read")
);
