I found many question about counting characters used in a string and solutions but how can I get all character used in string? Im new to JavaScript, im do not know to output this
for example
"English-Language" to "E,n,g,l,i,s,h,-,L,a,u,e" or "Javascript String" to "J,a,v,s,c,r,i,p,t, ,S,n,g"
Thank you..
Very simple with Set: (just cast it back to an array)
console.log([...new Set("English-Language")]);
console.log([...new Set("Javascript String")]);And if you want it as a single string, do this:
console.log([...new Set("English-Language")].join(","));
console.log([...new Set("Javascript String")].join(","));You can use the split function and the Set class to achieve this like so.
new Set("Javascript String".split(''))
The split('') part splits the string using an empty string as the seperator, so it just returns an array of all the characters. If you make a set from that array, it'll remove the duplicates. You can even pass the string directly to the Set constructor. If you want it as an array, just use Array.from.
you can simply use str.split("");
const str = 'English-Language';
str.split("");
Let me know if you face any future issue.
or Second option is
console.log([...new Set("English-Language")]);
