String Concatenation
Description :
Like Java and Python, you can concatenate Strings in Javascript as well.
If we have two strings "Hello " and "World", we can concatenate them using the
+ operator directly. This can also be acheived using the
concat(stringInTheMiddle, stringToBeJoined) method. Note the concat method
returns a new string and the original string remains unchanged
Syntax :
let added_string = original_string1 + original_string2;
let added_string = original_string.concat(middle_string, original_string2);
Examples :
let firstWord = "Hello ";
let secondWord = "World";
firstWord + secondWord = ??
let firstWord = "Hello ";
let secondWord = "World!";
let result = firstWord.concat(" ", secondWord);
result = ??
let firstWord = "Hello ";
let secondWord = "World!";
let result = firstWord.concat(" :) ", secondWord);
result = ??
