How to use String Concatenation In Javascript
This method utilizes string concatenation to insert a new string at a specific index. It involves splitting the original string into two parts based on the insertion index and then concatenating the new string in between these parts.
Example: In this example, we will split the string using concatenation.
// Input String
let origString = "GeeksGeeks";
// String to be added
let stringToAdd = "For";
// Position to add string
let indexPosition = 5;
// Construct the new string by concatenating the substrings
let newString = origString.substring(0, indexPosition) + stringToAdd + origString.substring(indexPosition);
// Display output
console.log(newString);
