Multiline Strings. Concatenating

Concatenating Multiple Lines

We can implement a multi-line string by concatenation of every line of the multi-line string to the variable. Below we have a code example for it:


              
1234

            
let  myStr = "This is my" +
   " multiline String " +
    " which is amazing";
console.log(myStr);
copy

Task

Take two variables named firstPart and secondPart and assign the values of "This is a" and " JavaScript book." respectively. The task is to concatenate the above variables using the + operator and store the concatenated string in a variable named book, and show value on the console.

Summary:

  • A string which comes on more than one line in the code is called Multiline String.
  • Template literals are used to implement multi-line string by using backticks.
  • Backslashes are used to implement multiline string.
  • Concatenation is used to implement multiline string.
