const value = 'Hello World'; const result = _.isString(value); // true
const value = 123; const result = _.isString(value); // falseIn this example, we declare a variable `value` and assign it the value `123`. We then use the `_.isString()` function to check if `value` is a string. The package library for Alloy.underscore can be determined by checking the imports at the top of the code file. If the library is imported using `import _ from 'underscore'` then it is the Underscore.js library. If it is imported using `import _ from 'lodash'` then it is the Lodash library.
