JQuery issue “TypeError: $.getJSON is not a function”

Question

I\'ve got this piece of code:

$(document).ready(function () {
    $.getJSON(\'http://localhost:5000/\', function (response) {
        console.log(response);

Thus happens commonly when migrating codebases from jQuery v1.x+ to v3.0+ as jQuery updated/deprecated/discontinued some of it's API.

I recommend using jQuery Migrate which will address this, along with other issues:

Get it here via CDN:

https://cdnjs.com/libraries/jquery-migrate

If using Gulp/Grunt, you can import into your project using

npm install --save jquery jquery-migrate

Github Repository - https://github.com/jquery/jquery-migrate
