You can use commas in the console.log() to add spaces You can set multiple variables (comma delimited) in the first argument of a ‘for’ loop myArray.forEach(function(entry){ console.log(entry.prop1, entry.prop2); }); // entry is the current object Note: ‘For’ loops are faster Some important JavaScript array methods… .filter() = Return a subset of an array based on the conditions […]
var numbers = [1, 4, 9]; var roots = numbers.map(Math.sqrt); // roots is now [1, 2, 3], numbers is still [1, 4, 9]

var testData = queryResponse.PrimaryQueryResult.RelevantResults.Table.Rows[0]; if (testData !== undefined) { return testData.Cells; } In this example, testData holds the result of the query so we can use it in a conditional and then return it without having to run the query again and again.
Node.js Install npm globally if you don’t already have it (check versions with node -v and npm -v) Run npm init command to initialize the package.json file to provide information about the project and help manage the dependencies… example… { “name”: “my_project”, “version”: “0.0.0”, “devDependencies”: { “gulp”: “~3.8.8” }, “dependencies”: { “jquery”: “~2.1.3”, “react”: “~0.13.1” } } devDependencies: These are […]

Using the minus or division math operator will coerce a string into a number … “123”-0 = 123 Never “==” to true or false, always “===”, because “==” will match falsy things like 0 == allows coercion (checks value) – implicit === disallows coercion (checks value and type) – explicit

SharePoint has a nasty habit of fooling JavaScript into thinking the DOM is loaded when there are actually still elements popping in afterwards. Here’s a dirty script for testing the existence of a given element when you’re in a pinch… var wnt_spTimer, wnt_spElement; wnt_spTimer = window.setInterval(function(){ wnt_spElement = $(‘div[data-widget=”tools”] .heading-main h2’).length; if(wnt_spElement === 0){ console.log(‘******** […]

You can create custom jQuery events with jQuery’s .on() method and then trigger your custom event with jQuery’s .trigger() method.
Event delegation is monitoring events on descendants via a common parent. This reduces overhead and allows for descendants not yet created to inherit the functionality.
