Magic numbers are one of those bad practices in programming that have somewhat of a weird name. After all, folks generally like magic, so it’s unclear what’s so bad about them. Fortunately, today we’ll talk about what a magic number is and how to remove them from your programs. ...
const val searchWeight = 2.4f // How specific your query must be. Increase this number to get more fuzzy results const val searchSpread = 10.234f // How spread the result are. Selects more words in a row in the database const val searchPageSize = 999 // The number of results we ...
Despite the super fun sounding name, magic numbers are a bad thing. It is anold school programming termfor “unnamed numerical constant”. As in, just some number plunked into the code that is probably vital to things working correctly but are very difficult for anyone not intimately familiar...
let startingNumberOfCards = 7 let maxNumberOfPlayers = 7 Even though 7 is the value for both of these constants, it represents different knowledge in different contexts and thus 2 different named constants are appropriate.ExceptionsAs with most “rules” in programming, there are exceptions....
