The 'is-string' npm package is a JavaScript utility that helps in validating if a certain value is a JavaScript String object or primitive. It has the feature to work cross-realm/iframe and regardless of ES6 @@toStringTag, adding more to its versatility and functionality.
To use 'is-string', you first need to install the package from npm using npm install is-string. After the successful installation, you can start using the isString function in your code. Here's an example of how you can utilize it:
var isString = require('is-string');
var assert = require('assert');
assert.notOk(isString(undefined)); // returns false
assert.notOk(isString(null)); // returns false
assert.notOk(isString([])); // returns false
assert.ok(isString('foo')); // returns true
assert.ok(isString(Object('foo'))); // returns true
In the example above, we first import the 'is-string' module and the 'assert' module. We use isString function with different types of values, and it will return either true or false based on if the said value is a String or not.
The documentation of 'is-string' is located on its npm package page. Extremely likely, the source code and other useful information can also be found on its GitHub repository (https://github.com/ljharb/is-string). For more details about the 'is-string' implementation and usage, you should visit these official links directly.
