It’s at the origin of a multitude of jokes and winks exchanged between initiates. The author’s choice of the number 42 has become a fixture of geek culture. To find out what happens next, you’ll have to read Adams’s books. The new version of the computer is Earth. To find the correct statement of the query whose answer is 42, the computer will have to build a new version of itself.
Yet, as the computer points out, the question itself was vaguely formulated. The characters tasked with getting that answer are disappointed because it is not very useful. Toward the end of the book, the supercomputer Deep Thought reveals that the answer to the “Great Question” of “Life, the Universe and Everything” is “forty-two.”ĭeep Thought takes 7.5 million years to calculate the answer to the ultimate question.

Take author Douglas Adams’s popular 1979 science-fiction novel The Hitchhiker’s Guide to the Galaxy, the first in a series of five. Moreover our interest holds even if the mystery is based on a joke. Examples include Amelia Earhart’s disappearance over the Pacific in 1937 and the daring escape of inmates Frank Morris and John and Clarence Anglin from Alcatraz Island in California in 1962. The semicolon in JavaScript is only required when two or more statements are on the same line.Everyone loves unsolved mysteries. When there is a return, break, throw, or continue statement on its own line.When the next line starts with a curly bracket, }, closing the current block.

When the next line starts with code that breaks the current one (code can spawn on multiple lines).The JavaScript parser automatically adds a semicolon when, during the parsing of the code, it comes across a few particular situations: It is important to know the rules that power semicolons, to avoid writing code that will generate bugs because JavaScript does not behave in an expected manner. These situations are described by saying that semicolons are automatically inserted into the source code token stream in those situations. When there is a place where a semicolon is needed, it quietly adds it behind the scenes.įor convenience, however, such semicolons may be omitted from the source text in certain situations. It does not mean that actual semicolons are inserted into the code.ĪSI is more of a set of rules used by JavaScript that will determine whether or not a semicolon will be interpreted in certain spots. The reason semicolons are sometimes optional in JavaScript is because of ASI. This school of thought declares the concept as a way to encourage good coding practices. There are many instances in JavaScript where semicolons are absolutely required, instances that the ASI feature will not take care of. The word never in the title, as is almost always the case, is not to be taken literally. Because the ASI feature will take care of the insertion negates the need to add superfluous punctuation. The assumption is that the documentation for the ASI clearly states the cases in which the feature is implemented. The second school of thought is that semicolons should only be used in cases where they are absolutely required.
School of Thought: 'Never Use Semicolons' If the ASI feature is altered or changed down the line, code that did not use semicolons may be operating under deprecated functionality. The assumption is that the ASI will never be 100% reliable, but also liable to change with each new version of JavaScript. This thought says that developers should always use semicolons, even in areas where automatic semicolon insertion (ASI) would normally take care of things. School of Thought: 'Always Use Semicolons'
To use semicolons as a readability feature?.The question becomes, is it a best-practice: There are two schools of thought on whether to insert semicolons into code as good practice. Programs must be written for people to read, and only incidentally for machines to execute. The simple fact is that I do not have any quantitative or qualitative data to prove one is better than the other. This article is about my "opinion." Semicolons should be included when writing JavaScript.
