JavaScript Code: // Function to return a random item from an arrayfunctionrandom_item(items){// Use Math.random() to generate a random number between 0 and 1,// multiply it by the length of the array, and use Math.floor() to round down to the nearest integerreturnitems[Math.floor(Ma...
You can simply use the Math.random() method in combination with the Math.floor() method to get a random item or value from an array in JavaScript.The Math.random() method returns a floating-point, pseudo-random number in the range 0 to less than 1 (inclusive of 0, but not 1), ...
function getRandomInt(min, max) { // Create byte array and fill with 1 random number var byteArray = new Uint8Array(1); window.crypto.getRandomValues(byteArray); // Convert to decimal var randomNum = '0.' + byteArray[0].toString(); // Get number in range randomNum = Math.floor...
crypto.getRandomValues()使用系统提供的加密安全的伪随机数生成器(CSPRNG)来获取随机数。 CSPRNG是一种专门设计用于密码学和安全应用的随机数生成器,具有良好的随机性和不可预测性。 由于使用系统级的安全随机数生成器,crypto.getRandomValues()生成的随机数更具安全性,不容易受到外部攻击。 4. 返回值类型 crypto.g...
