You can pass a separator as an argument of split() to let JavaScript know what character is used to split the string. See the following code: let myString = "Jack,James,Nathan" let stringToArray = myString.split(","); console.log(stringToArray); // [ 'Jack', 'James', 'Nathan'...
Passing a structure from managed code to JavaScript results in by-value behavior. The structure value is explicitly unboxed and copied over to JavaScript. Passing a JavaScript object to managed code, where the target type is a structure, results in by-value behavior and requires an explicit call...
