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){
length++;
}
return length;
}
console.log(strLength("Hello")); // 5
console.log(strLength("")); // 0
