I have wrote the function below, which takes a parameter (a string) and extracts certain data out of it.
function getTweetData(tweet) {
const newObject = {
tags: [],
mentions: [],
tagCount: 0,
mentionCount: 0,
length: 0,
};
//length
newObject.length = tweet.length;
const findMention = tweet.split("@").length - 1;
newObject.mentionCount = findMention;
const atRegex = tweet.match(/@(.[a-z0-9]+)/g);
newObject.mentions = atRegex === null ? [] : atRegex;
const findHashtag = tweet.split("#").length - 1;
newObject.tagCount = findHashtag;
const regex = tweet.match(/#(.[a-z0-9]+)/g);
newObject.tags = regex === null ? [] : regex;
//need to put the above two together
console.log(newObject);
return newObject;
}
The code takes a string and attempts to extract the amount of characters, the number of @ and the number of #. The @ and # contents should then be entered into the respective arrays (in const newObject).
The above code works for strings which contain either @ or # but not for strings which contain both.
Any ideas on how to combine the two.
The tests I have wrote are below, and all except the last one are passing.
const getTweetData = require("../get-tweet-data");
describe("Name of the group", () => {
test("should return return empty object", () => {
expect(typeof getTweetData(" ")).toBe("object");
});
test("should return length of character tweets", () => {
expect(getTweetData("tweet")).toEqual({
tags: [],
mentions: [],
tagCount: 0,
mentionCount: 0,
length: 5,
});
});
test("should return amount of hashtags mentioned in tweet", () => {
expect(getTweetData("tweet #coding")).toEqual({
tags: ["#coding"],
mentions: [],
tagCount: 1,
mentionCount: 0,
length: 13,
});
});
test("should return amount of @mentions mentioned in tweet", () => {
expect(getTweetData("tweet @coders")).toEqual({
tags: [],
mentions: ["@coders"],
tagCount: 0,
mentionCount: 1,
length: 18,
});
});
test("should return amount of @mentions and #hashtags mentioned in tweet", () => {
expect("Hello @stackoverflow #coding #needhelp").toEqual({
tags: ["#coding", "#needhelp"],
mentions: ["@stackoverflow"],
tagCount: 2,
mentionCount: 1,
length: 38,
});
});
});
Your function seems to work.
Here is the output we get when we call getTweetData on the string:
"Hello @stackoverflow #coding #needhelp"
{
tags: [ '#coding', '#needhelp' ],
mentions: [ '@stackoverflow' ],
tagCount: 2,
mentionCount: 1,
length: 38
}
Edit: There is a mistake in your last test: You should call:
expect(getTweetData("Hello @stackoverflow #coding #needhelp")).toEqual({ ...
instead of expect("Hello @stackoverflow #coding #needhelp").toEqual({ ...
