Question

Write a JavaScript function that checks if a given string, ends with a given substring.

The input comes as 2 string arguments:

• The first string will represent the main one
• The second one will represent the substring.

Examples:

Input:
This sentence ends with fun?
fun?

Output:
true

---

Input:
This is Houston, we have…
We have…

Output:
false

---

Input:
The new iPhone has no headphones jack.
o headphones jack.

Output:
true

---

The output is either “true” or “false” based on the result of the check. The comparison is case-sensitive!

Answer 1

My javascript code:

function checkEnd(data, checkData) {
    let check = data.substr(data.length - checkData.length, data.length);

    if (check == checkData) {
        console.log(true);
    } else {
        console.log(false);
    }
}

//checkEnd("This sentence ends with fun?", "fun?");
checkEnd("This is Houston, we have…","We have…");
