The idea is that we get a string and have to return the string without the letters
Let's dive right into the solution.
const input = 'daily dev tips'; const removeVowels = input.replace(/[aeiou]/gi, ''); console.log(removeVowels); // 'dly dv tps'
It works! And yep that's all the code we need, but let's take a closer look at how it works.
We could, say, replace the letter
i with an empty string like this.
const removeVowels = input.replace('i', ''); console.log(removeVowels); // 'daly dev tips'
However, you'll notice it only replaced the first occurrence. And, of course, we can only target one letter at a time. So this is where our regular expression comes in.
We start the regular expression by wrapping it in the
/ / backslashes.
Then we open a pattern matcher with the
 brackets. And in between, we specify which letters should be matched.
The last part is to use
gi at the end, which stands for
globalmeaning to apply it to each occurrence, not just the first one
ignoremeans to perform a case-insensitive search
