I've got the following array :
[David, Daniel, Dude, Dwayne]
How do I get a list of the names that starts with "Da"? The output should be :
[David, Daniel]
Thanks.
You can use .filter() as -
["David", "Daniel", "Dude", "Dwayne"].filter((element)=> element.startsWith('Da'))
Outputs
Array [ "David", "Daniel" ]
The filter function is applied on an array. Inside this, we are just checking if the element starts with Da, if that condition returns false, the function will filter that element out.
