There are a number of ways to convert a string to its Unicode representation in JavaScript, depending on the desired format of the output. Here are a few approaches, each with explanations and examples: Method 1: Using charCodeAt() for individual characters This method iterates through each character in the string and uses charCodeAt() to get its Unicode code point. It's suitable when you need the individual code points for each character. function stringToUnicodeCodePoints(str) { let codePoints = []; for (let i = 0; i < str.length; i++) { codePoints.push(str.charCodeAt(i)); } return codePoints; } let myString = "Hello, world!"; let unicodePoints = stringToUnicodeCodePoints(myString); console.log(unicodePoints); // Output: [72, 101, 108, 108, 111, 44, 32, 119, 111, 114, 108, 100, 33] Explanation: The function stringToUnicodeCodePoints takes a string str as input. It initializes an empty array codePoints to store the Unicode code points. ...
Quantum computing has seen remarkable progress in recent years. After the first demonstrations of “quantum supremacy” or “quantum advantage”, companies are now publishing roadmaps projecting commercial quantum computers with millions of qubits within a decade. Meanwhile, new quantum computing approaches based on photons, atoms and topology are catching up to the early leaders using superconducting circuits and ion traps. The fundamental building blocks of quantum computers are qubits (quantum bits). Unlike regular bits, qubits can exist in a superposition of 0 and 1, allowing massive parallelism. When entangled together, qubits enable certain computations like simulation of quantum systems to be done exponentially faster. The catch is quantum states are fragile and error-prone. The threshold for useful applications is estimated to be between hundreds of thousands to millions of physical qubits. In 2019, Google announced its 53-qubit Sycamore processor achieved quantum supremacy by...
