这是 Eloquent JavaScript 第 3 章中的代码片段。

const power = function(base, exponent) {
  let result = 1;
  for (let count = 0; count < exponent; count++) {
    result *= base;
  }
  return result;
};
console.log(power(2, 10));
// 1024

我是这样向自己解释的。但是我无法真正理解为什么返回 1024 somoene 可以帮我分解它吗？

/* 
    Explanation of code above.

     - We created a function named power. We used a function expression notation to create it. 
     
     - power has two parameters base and exponent.

     - the body of the function contains the code that the function will execute. 

    - the body does the following:

        1. declares a variable called result which has a value of 1.
        
        2. There is a for loop. Here are the parts of the for loop:

            - The intializer: the variable count is declared and assigned a value of 0

            - We are looking at the condition to see if it is truthy. The condition is whether count is greater than exponent. The loop will continue to iterate until this condition is truthy.

            - The incrementer: count will go up by 1 each iteration of the loop

            - The body of the for loop (the code to be executed) states that the result variable is equal to result *= base OR result = result * base 
    
    - then the function will return the value of result 

    - we are done with the function 

    - outside of the function we invoke it using console.log() and pass it the arguments 2 and 10 (base, exponent). 

    - The computer plugs the arguments into the function. The computer evaluates the condition in the for loop to see if its truthy. Basically, the computer asks is count < exponent? Count = 0 and exponent = 10. So the condition evaluates to falsey. 


    const power = function (2, 10) {
    let result = 1;
    for (let count = 0; 11 < 10; count++) {
                    1   10
                    2   10
                    3   10
                    4   10
                    5   10
                    6   10
                    7   10
                    8   10
                    9   10
                    10  10
                    11  10
                    
        result *= base; => 2 = 2 * 10
    }
    return result;

};

console.log(power(2,10));

我期待结果 *= 基数，或结果 = 结果 * 基数。我知道我在迭代中遗漏了一些东西。
