If you need to clamp a number to keep it inside a specific range boundary function clamp(min, max, val) { return Math.min(Math.max(min, +val), max); } console.log(clamp(-10, 10, "4.30")); // 4.3 console.log(clamp(-10, 10, -8)); // -8 console.log(clamp(-10, 10, 12)); // ...

To make long text at most N characters long but leave last word intact, use .{0,N}\b pattern: ^(.{0,N})\b.*

Before making a pull request, it is useful to make sure that compile is successful and tests are passing for each commit in the branch. We can do that automatically using -x parameter. For example: git rebase -i -x make will perform the interactive rebase and stop after each commit to execute mak...

go run will run a program without creating an executable file. Mostly useful for development. run will only execute packages whose package name is main. To demonstrate, we will use a simple Hello World example main.go: package main import fmt func main() { fmt.Println("Hello, World...

go clean will clean up any temporary files created when invoking go build on a program. It will also clean files left over from Makefiles.

A panic halts normal execution flow and exits the current function. Any deferred calls will then be executed before control is passed to the next higher function on the stack. Each stack's function will exit and run deferred calls until the panic is handled using a deferred recover(), or until the...

Let's take a sample class: public class Transaction { public string Category { get; set; } public DateTime Date { get; set; } public decimal Amount { get; set; } } Now, let us consider a list of transactions: var transactions = new List<Transaction> { new Transaction...

int signed_integer = -1; // The right shift operation exhibits implementation-defined behavior: int result = signed_integer >> 1;

// Supposing SCHAR_MAX, the maximum value that can be represented by a signed char, is // 127, the behavior of this assignment is implementation-defined: signed char integer; integer = 128;
