check if string has quotes javascript

Looks like we are checking if sting is like this

"some string"

or

'some string'

To detect the quotes we can use this code

let string = "some string";

if(string.indexOf('"') > -1){
 
 // then do something

}

or simply use

if(string[0] === '"' && string[string.length-1] === '"'){

 // then do something

}

If you want to find out if string contains quote or not you might like this

let string = 'Some string " with double quote';

if(string.indexOf('"') > -1){

 // Check this and do something.

}

Hope this helps.
