With a string, ex: data
. I want to insert all new characters in an array, respecting the example I gave the answer should be:
characters = ["d","a","t"];
I did the following up to now:
const balanced = string => {
var characters = [];
var characters_Counter = 0;
for (var i = 0; i < string.length; i++) {
if (string.charAt(i) != characters){
characters[characters_Counter] = string.charAt(i);
characters_Counter++;
}
console.log(characters[i]);
}
};
In the if
I want to compare string.charAt(i)
with all the elements inside characters[]
and if it is a new character do the if
's content. The problem is: I'm stuck, I can't think a way to make this comparison work.
Use the includes()
method to check if an element (character) is inside an array
const balanced = string => {
var characters = [];
var characters_Counter = 0;
for (var i = 0; i < string.length; i++) {
if (!characters.includes(string.charAt(i))) { // <------ here
characters[characters_Counter] = string.charAt(i);
characters_Counter++;
console.log(characters[i]);
}
}
};
balanced("data");
