如何找到某个值并将其替换，并将所有值推入一个新数组？

function replaceAndPush(array, targetValue, replacementValue) {
  var newArray = [];
  
  for (var i = 0; i < array.length; i++) {
    if (array[i] === targetValue) {
      newArray.push(replacementValue);
    } else {
      newArray.push(array[i]);
    }
  }
  
  return newArray;
}

// 示例用法
var originalArray = [1, 2, 3, 4, 5];
var targetValue = 3;
var replacementValue = 6;

var newArray = replaceAndPush(originalArray, targetValue, replacementValue);
console.log(newArray); // 输出 [1, 2, 6, 4, 5]
