Explore the core features of Docker Hardened Images, including hardened defaults, secure metadata, and ecosystem compatibility.

The Object.freeze() static method freezes an object. Freezing an object prevents extensions and makes existing properties non-writable and non-configurable. A frozen object can no longer be changed: new properties cannot be added, existing properties cannot be removed, their enumerability, configurability, writability, or value cannot be changed, and the object's prototype cannot be re-assigned. freeze() returns the same object that was passed in.

The Math.log() static method returns the natural logarithm (base e) of a number. That is

The ignoreCase accessor property of RegExp instances returns whether or not the i flag is used with this regular expression.

The unicodeSets accessor property of RegExp instances returns whether or not the v flag is used with this regular expression.

Docker Scout can integrate with runtime environments to give you real-time insights about your software supply chain.

The Atomics.xor() static method computes a bitwise XOR with a given value at a given position in the array, and returns the old value at that position. This atomic operation guarantees that no other write happens until the modified value is written back.

The Atomics.or() static method computes a bitwise OR with a given value at a given position in the array, and returns the old value at that position. This atomic operation guarantees that no other write happens until the modified value is written back.

The String.fromCodePoint() static method returns a string created from the specified sequence of code points.
