I need to remove duplicate words in a string, but not the numeric characters.
Here's an example of text that I need to convert and keep the numeric characters. Any suggestions on how to handle this?
String example: "Rim - Rim Black 28H 700mm x 700mm"
static removeDuplicateWords = (statement: string) => {
return statement
.split(" ")
.filter((item, pos, self) => {
return self.indexOf(item) === pos;
})
.join(" ");
};
Current Results: - Rim Black 28H x 700mm
Expected results: - Rim Black 28H 700mm x 700mm
Thanks for the help
Use a regular expression to test if the word contains a digit.
static removeDuplicateWords = (statement: string) => {
return statement
.split(" ")
.filter((item, pos, self) => item.match(/\d/) || self.indexOf(item) === pos)
.join(" ");
};From your example, you can create a set of the split string and join it again.
console.log(Array.from(new Set("Rim - Rim Black 28H 700mm x 700mm".split(' '))).join(' '))
// print 'Rim - Black 28H x 700mm'
