So it turns out triple-byte is weird and I apparently have passed the quiz already. But im pretty sure they said i did not the first time I took it. But anyway, The picture i posted before are for the second attempt quiz. i got the first attempt quiz done, Here it is with accompanying screenshots. . cookies maxnum = num bar get json.parse() a/b testing #4, the compile to css but provide convenient syntax for nesting variable and other features. larry moe curly #3, ouptut.push(list[i-1] + output[i]) #4 return function(y){return x+y; } #1 webpack is a module bundler whereas bable is a javascript compiler. Oauth is a service that will let you give acces to a third party app without actually giving them your sing in credentials. there is a question about matrix multiplication question, having a super hard time finding out what that is the answer is 120, closures will only call the number of arguments deep you give them. also x*=4 is an assingment, so even if you say var t = x*=4, t will be x times 4, but so will x. there was a question about cors, I tried to research what the answer was, and now I am more confused than ever, but Im not sure its that important to know cors backwards and forwards. the answer is to server crom a CDN to leverage their infrastrucutre. CDN adds security and decreases load and increases speed by distributing your content closer to the points from which it will be accessed. async awain is syntacctic sugar for promises that allows you to write synchronou looking callback code recursive arrow function, const f = n => n <= 1 ? 1 : n * f(n - 1); let g = f(4) result is 24. pink square stacked horizontally In computing, memoization or memoisation is an optimization technique used primarily to speed up computer programs by storing the results of expensive function calls and returning the cached result when the same inputs occur again Bytecode is program code that has been compiled from source code into low-level code designed for a software interpreter. It may be executed by a virtual machine (such as a JVM) or further compiled into machine code, which is recognized by the processor. Margin auto will horizontally center a fixed sized elemetn inside its parent parsefloat() is the answer return parseFloat(str) a function called with extra aguments just uses number that it was expecting, a function called with fewer argumetns just uses the ones that it is passed and puts undefined for the rest. calling settimeout still holds for the line following even if it is set to 0 so if its test(1) setTimeout(function(){test(2)}, 0) test(3) then the result is 132 because settimeout still pauses. A skip list is a sorted linked list with saved values periodically so you can do lookups much faster by jumping to the value that is one smaller than the element we are looking for. #4, a polyfill implememtnts an api so that developer can builda aginst a consistent interface, even on unsupported browsers. #2 exhaustion of ipv4 addresses its W. filter removes things that dont match the condition, map performs an opperation on each item, and reduce makes it all one thing. this is caused by javascripts hoisting mehcanism. |
