template literals in javascript
Using JavaScript, we can shorten the length of our string and just replace the rest with three dots.
let stringVal = "Hello Codeflare!";
shortenString = stringVal.substring(0, 3).concat('...');
console.warn(shortendString) //Hel...
We’re achieving this using the substring() and concat() method.
The substring()
method extracts characters, between two indices (positions), from a string, and returns the substring and does not change the original string.
The substring()
method extracts characters from start to end (exclusive).
The concat() method is used to join two or more strings.
So what we’re doing here is that after trimming the length of the string to whatever position we have set, we’re then just joining the result with the three dots.
This is how we shorten string with three dots in Javascript.
