How can I cut a string after X characters in JavaScript?
To cut a string after X characters, use substr() function from JavaScript. Following is the JavaScript code wherein we are cutting the string after 9th character −
Example
var myName="JohnSmithMITUS";
console.log("The String="+myName)
var afterXCharacter = myName.substr(0, 9) + "\u0026";
console.log("After cutting the characters the string="+afterXCharacter);Above, the unicode “\u0026” will replace all the characters with &(“\u0026”).
