How to Append a String to another String in TypeScript - Step by Step Examples



How to Append a String to another String in TypeScript ?

Answer

To append a string to another string in TypeScript, you can use the concat method or the += operator to concatenate the strings.



✐ Examples

1 Append " World" to "Hello"

In this example,

  1. We create a variable named str1 with a value of "Hello".
  2. We then use the concat method to append the string " World" to str1.
  3. The concat method concatenates the two strings and returns the result.
  4. Finally, we print the concatenated string to the console.

TypeScript Program

let str1: string = "Hello";
str1 = str1.concat(" World");
console.log(str1);

Output

Hello World

2 Append "apple" to "banana"

In this example,

  1. We create a variable named str2 with a value of "banana".
  2. We then use the += operator to append the string "apple" to str2.
  3. The += operator concatenates the two strings and assigns the result to the variable str2.
  4. Finally, we print the updated string to the console.

TypeScript Program

let str2: string = "banana";
str2 += "apple";
console.log(str2);

Output

bananaapple
