const string = "Name".slice(0, 250).concat('...');
const string2 = "Name".substring(0, 250).concat('...');var string = "ABCDEFG";
var truncString = string.substring(0, 3); //Only keep the first 3 characters

}const truncate = (str, max, suffix) => str.length < max ? str : `${str.substr(0, str.substr(0, max - suffix.length).lastIndexOf(' '))}${suffix}`;
// Example
truncate('This is a long message', 20, '...'); function truncateString(str, num) {
if (str.length > num) {
return str.slice(0, num) + "...";
} else {
return str;
}

const str = 'Mozilla';
console.log(str.substring(1, 3));
// expected output: "oz"
console.log(str.substring(2));
// expected output: "zilla"
