How do you reverse a string in-place in JavaScript?
(57 answers)
Closed 3 years ago.
I would like to sort strings in javascript containing comma separated values in different e.g.
var Str = "8,0,2,10"
I want to sort it like below example form the last one to first one:
var NewStr = "10,2,0,8"
You can convert string to array using split() and reverse the array element using reverse() and then convert result to string again using join() like this:
var Str = '8,0,2,10';
var dif = Str.split(',').reverse().join(',');
console.log(dif);

Get Substring between two characters using javascript
(24 answers)
Closed 4 years ago.
I need to iterate over strings that are inside an array, to get a sub-string in each string.
Substrings are between "()"
Something like this..
let myArray = ["animal(cat)", "color(red)", "fruits(apple)"];
//return
//'cat','red','apple'
How I could do that?
You can do this using substring and lastIndexOf functions.
let myArray = ["animal(cat)", "color(red)", "fruits(apple)"];
myArray.forEach(function(e){
console.log(e.substring(e.lastIndexOf("(") + 1, e.lastIndexOf(")")))
})
