The decrement operator in Javascript decreases an integer value by one. This operator is often utilized in loops, counters, and mathematical computations where a value has to be decreased sequentially. Types of Decrement Operators The decrement operator (--) can be used in two ways ? Post-...
Can I use decrement in different programming languages? Yes, the decrement operator is available in many programming languages, including C, C++, Java, JavaScript, Python, and more. However, the syntax may vary slightly between languages. In C-based languages, it's "--" (double minus), whil...

Also, the main point of this operator in the C-family languages is to use in a for loop (and similar constructs). In GDScript you do a for loop without having to increment it manually so it's not as important (the same happens in Python). This may be connected to use case in #27...

value to the left is falsy, while the nullish coalescing operator will return the value to the right only if the value to the left is null or undefined. The falsy values in JavaScript are:false,null,undefined,0,"", andNaN. All other values are truthy. The following code illustrates this...
