Показать описание
A strict mode in JavaScript is a special mode which makes it easier to write “secure code”. In simple words, strict mode changes previously accepted "bad syntax" into real errors.

In order to activate strict mode, we can write a string ‘use strict’ in the beginning of the script.

In this way, we activated strict mode for the entire script. This statement has to be the very first statement in the script. If we have any code before this, then strict mode will not be activated. Comments are allowed because JavaScript will just ignore them but no code.

DEAR SIR, I STARTED THIS SECTION TODAY, BUT IT SIMPLY DOES NOT WORK IN EDGE. I HAVE NOT TRIED IN CHROME YET AND I DON'T KNOW WHY THE STRICT MODE DOES NOT WORK AT ALL! COULD IT BE, THAT IT IS NOT USED ANY LONGER IN JS? THANKS IN ADVANCE FOR YOUR KIND ANSWER!
