Using UTF-16 range and the charCodeAt() method:

The UTF-16 range for the amharic letters are from 4608 to 5017 and from 11648 to 11743 so you can use the charCodeAt() method to check if the string characters fall within those two ranges or not.

Check and run the following Code Snippet for a practical example of what I described above:

var string = "የሙከራ test ሕብረቁምፊ";

function checkAmharic(x) {
    let flag = false;   
    [...x].forEach((e, i) => {
    	if (((e.charCodeAt(i) > 4607) && (e.charCodeAt(i) < 5018)) || ((e.charCodeAt(i) > 11647) && (e.charCodeAt(i) < 11743))) {
      	if (flag == false) {
        	flag = true;
        }
      }
    })
    return flag; 
}

console.log(checkAmharic(string)); // will return true
console.log(checkAmharic("Hello All!!")); // will return false

Using ASCII range and regex:

The ASCII range for the amharic letters are from 1200 to 137F so you can use regex to check if the string characters fall within those two ranges or not.

Check and run the following Code Snippet for a practical example of what I described above:

var string = "የሙከራ test ሕብረቁምፊ";

function checkAmharic(x) {
    return /[\u1200-\u137F]/.test(x); // will return true if an amharic letter is present
}

console.log(checkAmharic(string)); // will return true
console.log(checkAmharic("A")); // will return false
