An example Analysis of the Operation of b in weakly typed language javascript

Editor to share with you the weakly typed language javascript in the aforme b operation example analysis, I believe that most people do not know much about it, so share this article for your reference, I hope you will learn a lot after reading this article, let's go to understand it!

The details are as follows:

Here are seven small closure functions to test the output of aformab

Test 1: (when an is true,b and false, the output is false)

! function () {var a = true,b = false; console.log ((var b) + 'test1'); / / false test1} ()

Test 2: (when an is true,b and true, the output is true)

! function () {var a = true,b = true; console.log ((var b) + 'test2'); / / true test2} ()

Test 3: (when an is false,b and true, the output is true)

! function () {var a = false,b = true; console.log ((var b) + 'test3'); / / true test3} ()

Test 4: (when an is false,b and false, the output is true)

! function () {var a = false,b = false; console.log ((var b) + 'test4'); / / false test4} ()

Test 5: (when an is false,b, the string is output)

! function () {var a = false,b = ''; console.log ((AMaginb) +' test5'); / / test5} ()

Test 6: (when an is a string and b is false, the output is false)

! function () {var a = '',b = false; console.log ((var b) +' test6'); / / false test6} ()

Test 7: (when an is true,b and empty string, the output is empty string)

! function () {var a = true,b =''; console.log ((AMagneb) + 'test7'); / / test7} ().
