npm v7

Version update from v8 to v8 9.0

With the profound performance enhancements, it also brings the introduction of new features.

For instance,

In particular, the improvement has brought ECMAScript RegExp to match the indices; you find the indices array property through .indices and then match both the objects when it shows /d as the regular expression flag.

> const matchObj = /(Java)(Script)/d.exec(‘JavaScript’); undefined > matchObj.indices [ [ 0, 10 ], [ 0, 4 ], [ 4, 10 ], groups: undefined ] > matchObj.indices[0]; // Match [ 0, 10 ] > matchObj.indices[1]; // First capture group [ 0, 4 ] > matchObj.indices[2]; // Second capture group [ 4, 10 ]

NodeJS v16 has also introduced a particular feature to deal with regular expressions.

Access to the indices array could be possible through the indices property.

const regex = /(a)(b)/d; const match = regex.exec(“xy”); console.log(match.indices[0]); // [0, 2] console.log(match.indices[1]); // [0, 1] console.log(match.indices[2]); // [1, 2]

One must need to use util.promisify() to remove the need to use an alternative set of timers.

import { setTimeout } from ‘timers/promises’; async function run() { await setTimeout(5000); console.log(‘Hello, World!’); } run();

Platform Minimums:

Nodejs uses predefined binary for several platforms, and with each significant release, the appropriate toolchain has been raised and used when necessary.

This is the first significant release where the binaries have been shipped to Apple Silicon. In contrast, separate tarballs will be provided for intel and ARM.
