The Great Chrome Dev Tool

Chrome dev tool is not only super useful for front-end dev but also helpful to users.

contentEditable

By setting

document.body.contentEditable = true

the function

console.table(arraydata)

give us a table that is associated with the array.

clear()

inspect()

inspect($('.sidebar'))

will list all the element that has class sidebar.

dir()

List out all the properties of a element using

dir($("div"))
