how to use the isstring function from the underscore library in javascript

To use the isString function from the Underscore.js library in JavaScript, you will first need to include the Underscore library in your project. Once you've included the library, you can call the isString function and pass in the value you want to check for its type.

Here is an example code snippet that demonstrates how to use the isString function:

index.tsx
// include the Underscore library
const _ = require('underscore');

// create a variable with a string value
const myString = 'Hello, world!';

// check if the variable is a string using the `isString` function
if (_.isString(myString)) {
  console.log('myString is a string!');
} else {
  console.log('myString is not a string!');
}
334 chars
13 lines

In this example, we first include the Underscore library using the require function (assuming you are using Node.js). We then create a variable myString with a string value, and we use the isString function to check if myString is a string. We then log the appropriate message to the console depending on the result of the check.
