var str = 'Some very long string';
if(str.length > 10) str = str.substring(0,10);var example = "I am too long string";
var result;
// Slice is JS function
result = example.slice(0, 10)+'...'; //if you need dots after the string you can addfunction strLength(s) {
var length = 0;
while (s[length] !== undefined){

return length;

console.log(strLength("Hello")); // 5
