PHP's echo in JavaScript

How to use

You you can install via yarn add locutus and require this function via const echo = require('locutus/php/strings/echo').

It is important to use a bundler that supports tree-shaking so that you only ship the functions that you actually use to your browser, instead of all of Locutus, which is massive. Examples are: Parcel, webpack, or rollup.js. For server-side use this is typically less of a concern.

Examples

Please note that these examples are distilled from test cases that automatically verify our functions still work correctly. This could explain some quirky ones.

#	code	expected result
1	echo('Hello world')	undefined

Notes

• In 1.3.2 and earlier, this function wrote to the body of the document when it was called in webbrowsers, in addition to supporting XUL. This involved >100 lines of boilerplate to do this in a safe way. Since I can’t imageine a complelling use-case for this, and XUL is deprecated I have removed this behavior in favor of just calling console.log

• You’ll see functions depends on echo instead of console.log as we’ll want to have 1 contact point to interface with the outside world, so that it’s easy to support other ways of printing output.

Here’s what our current JavaScript equivalent to PHP's echo looks like.

module.exports = function echo() {

}

A community effort

Not unlike Wikipedia, Locutus is an ongoing community effort. Our philosophy follows The McDonald’s Theory. This means that we assimilate first iterations with imperfections, hoping for others to take issue with-and improve them. This unorthodox approach has worked very well to foster fun and fruitful collaboration, but please be reminded to use our creations at your own risk. THE SOFTWARE IS PROVIDED "AS IS" has never been more true than for Locutus.
