此Array.findIndex()方法可用於查找數組中素數的元素的索引(如果沒有素數則返回-1)。 讓我們看一下JavaScript程序: // function isPrime is used to find which// number is prime or not prime.functionisPrime(n){if(n ===1) {returnfalse; }elseif(n ===2) {returntrue; }else{for(varx =2; x...
Date ranges as well as numeric.includes(x) {returnthis.from<= x && x <=this.to; },// A generator function that makes instances of the class iterable.// Note that it only works for numeric ranges.*[Symbol.iterator]() {for(letx =Math.ceil(this.from); x <=this.to; x++)yieldx...
