Malicious npm Packages Inject SSH Backdoors via Typosquatted Libraries
Socket’s threat research team has detected six malicious npm packages typosquatting popular libraries to insert SSH backdoors.
Compare numbers, arrays, or nested arrays for equality up to some tolerance. Checks both shapes and values. Uses almost-equal and generalizes array-almost-equal. Useful when working with lists of coordinates and other numerical data.
use npm
npm install allclose
allclose(a, b, [atol], [rtol])
requires two numbers or arrays or nested arrays a
and b
, and optionally an absolute tolerance atol
and a relative tolerance rtol
. returns true
if a
and b
have the same shape and value, and false
otherwise.
you can test numbers
allclose(1, 1)
> true
allclose(1, 2)
> false
or arrays
allclose([1, 2], [1, 2])
> true
allclose([1, 2], [1, 2, 3])
> false
allclose([1, 2], [1, 3])
> false
or nested arrays
allclose([[1, 2], [3, 4]], [[1, 2], [3, 4]])
> true
allclose([[1, 2], [3, 4]], [[1, 2], [3, 4], [5, 6]])
> false
allclose([[1, 2], [3, 4]], [[1, 2], [3, 5]])
> false
and you can optionally specify a tolerance
allclose([1, 2], [1, 2.1])
> false
allclose([1, 2], [1, 2.1], 0.2)
> true
