Usage

Pass in an array and a predicate function. The function returns a new array excluding elements that satisfy the predicate without mutating the original array.

import * as
import _
_
from 'radashi'
const
const numbers: number[]
numbers
= [1, 2, 3, 4, 5]
const
const oddNumbers: number[]
oddNumbers
=
import _
_
.
function remove<number>(array: readonly number[], predicate: (value: number) => boolean): number[]

Removes elements from an array based on the specified predicate function.

@seehttps://radashi.js.org/reference/array/remove

@example

// Example 1: Remove even numbers from an array
const numbers = [1, 2, 3, 4, 5];
const result = remove(numbers, value => value % 2 === 0);
console.log(result); // Output: [1, 3, 5]
// Example 2: Remove objects with a specific property value
const items = [
{ id: 1, active: true },
{ id: 2, active: false },
{ id: 3, active: true }
];
const result = remove(items, item => item.active);
console.log(result); // Output: [{ id: 2, active: false }]

var console: Console

The console module provides a simple debugging console that is similar to the JavaScript console mechanism provided by web browsers.

The module exports two specific components:

  • A Console class with methods such as console.log(), console.error() and console.warn() that can be used to write to any Node.js stream.
  • A global console instance configured to write to process.stdout and process.stderr. The global console can be used without importing the node:console module.

Warning: The global console object's methods are neither consistently synchronous like the browser APIs they resemble, nor are they consistently asynchronous like all other Node.js streams. See the note on process I/O for more information.

Example using the global console:

console.log('hello world');
// Prints: hello world, to stdout
console.log('hello %s', 'world');
// Prints: hello world, to stdout
console.error(new Error('Whoops, something bad happened'));
// Prints error message and stack trace to stderr:
// Error: Whoops, something bad happened
// at [eval]:5:15
// at Script.runInThisContext (node:vm:132:18)
// at Object.runInThisContext (node:vm:309:38)
// at node:internal/process/execution:77:19
// at [eval]-wrapper:6:22
// at evalScript (node:internal/process/execution:76:60)
// at node:internal/main/eval_string:23:3
const name = 'Will Robinson';
console.warn(`Danger ${name}! Danger!`);
// Prints: Danger Will Robinson! Danger!, to stderr

Example using the Console class:

const out = getStreamSomehow();
const err = getStreamSomehow();
const myConsole = new console.Console(out, err);
myConsole.log('hello world');
// Prints: hello world, to out
myConsole.log('hello %s', 'world');
// Prints: hello world, to out
myConsole.error(new Error('Whoops, something bad happened'));
// Prints: [Error: Whoops, something bad happened], to err
const name = 'Will Robinson';
myConsole.warn(`Danger ${name}! Danger!`);
// Prints: Danger Will Robinson! Danger!, to err

console
.
Console.log(message?: any, ...optionalParams: any[]): void (+1 overload)

Prints to stdout with newline. Multiple arguments can be passed, with the first used as the primary message and all additional used as substitution values similar to printf(3) (the arguments are all passed to util.format()).

const count = 5;
console.log('count: %d', count);
// Prints: count: 5, to stdout
console.log('count:', count);
// Prints: count: 5, to stdout

See util.format() for more information.
