If callbackFn never returns a truthy value, find () returns undefined. find () then returns that element and stops iterating through the array. It calls a provided callbackFn function once for each element in an array in ascending-index order, until callbackFn returns a truthy value. This function checks the conditions and gets all the elements instead of the first one. The find () method is an iterative method. Function declares with an array and object key and value.

It has the ‘ this’ parameter which supplies the object and changes the default context. Since the module lookups using nodemodules folders are all relative. This function accepts the callback function to apply the search condition. CommonJS modules are the original way to package JavaScript code for Node.js.
