To avoid unexpected string concatenation while concatenating strings, multiple strings, and numbers, use backticks.
We have the following −
const concatValue = 'John,David,Mike'; var friendNames= `${concatValue}`;
The above value is concatenated with a string and number −
var studentNameWithFriends=` ${concatValue}| 'Carol' | 24 ` ;
Following is the complete JavaScript code for concatenation −
Example
const concatValue = 'John,David,Mike'; var friendNames= `${concatValue}`; var studentNameWithFriends=` ${concatValue}| 'Carol' | 24 ` ; console.log(friendNames); console.log(studentNameWithFriends);
To run the above program, you need to use the following command −
node fileName.js.
Here, my file name is demo37.js
Output
This will produce the following output −
PS C:\Users\Amit\JavaScript-code> node demo37.js John,David,Mike John,David,Mike| 'Carol' | 24
