Two words in the code 'equals' should be 'equal', remove the 's' in the end of the wordįor (var i = 0, l = nums.

use: var viewer = elem('.screen') because you will get an array of DOM objects by className, you need the first one.

use: var equal = elem('.equal') because you will get an array of DOM objects by className, you need the first one.

Today we are jumping straight into the basic project setup.

add var before declaring variables: equal to viewer use: var viewer elem ('.screen') 0 because you will get an array of DOM objects by className, you need the first one declare var viewer elem ('. In the last article, I shared my reasons for fully investing myself in the vanilla JS techniques again, after over a decade of working with JavaScript frameworks.

We can use CSS Grid to make the keys, since they’re arranged in a grid-like format.

Memory = parseFloat(memory.substring(0,findmaxlength(memory))) ĭ = memory ĭ = "ERROR" The calculator consist of two parts: the display and the keys. Then to get the age of a person in Milliseconds subtract DOB. I create 2 new variables millisecondsBetweenDOBAnd1970 and millisecondsBetweenNowAnd1970 to store number of milliseconds between DOB/NOW and Janurespectively. If (location.indexOf("-", 0) != -1) maxlength++ The Dat e.now () method returns the number of milliseconds since January 1, 1970.
