从 Basic 转换为 Javascript？

Question

晚安，

我需要从 基本进入javascript。 Javascript 没有 支持“转到”指令。我会 如果您能给我翻译，将不胜感激。 非常感谢

10 c = 1666.66
20 b = 1.007897747
30 a = 10000
40 n = 6
50 a = a * b
60 a = a -c
70 n = n -1
80 c = c + 0.01
90 if a <= 0 then 120
100 if n = 0 then 30
110 goto 50
120 print c
130 end

Answer 1

此提案具有无限 while 循环与 for 循环和退出的组合。

function x() {
    var a, b, c, n;
    c = 1666.66;
    b = 1.007897747;
    while (true) {
        a = 10000;
        for (n = 6; n--;) {
            a *= b;
            a -= c;
            c += 0.01;
            if (a <= 0) {
                return c;
            }
        }
    }
}
document.write(x());

为了证明结果，您可以复制下面的代码并将其插入到在线 BASIC 解释器中，例如 http://www.quitebasic.com/

10 let c = 1666.66
20 let b = 1.007897747
30 let a = 10000
40 let n = 6
50 let a = a * b
60 let a = a -c
70 let n = n -1
80 let c = c + 0.01
90 if a <= 0 then 120
100 if n = 0 then 30
110 goto 50
120 print c
130 end

Answer 2

这是一种方法

 // store the information in an Object, so that data can be migrated easily
    var dataSet = setInitialValues(); 

    // perform the calculation, this is a recursive function  
    performCalculations(dataSet);
    
    // definition for function that create the initial data set
    function setInitialValues(){
    	return {
    			c: 1666.66,
    			b : 1.007897747,
    			a : 10000,
    			n : 6
    		}
    }
    
    // reassign value to a and n, called when n reached 0
    function reSetValues(d){
    	d.a = 10000;
    	d.n = 6;
    	return d	
    }
    
    // recursive function, operates on the data set
    function performCalculations(d){
    	d.a = d.a*d.b;
    	d.a = d.a-d.c;
    	d.n = d.n-1;
    
    	d.c = d.c+0.01;
    	
    	if (d.a<= 0){
    		document.write(d.c)
    	} else if(d.n==0){
    		reSetValues(d);
    		performCalculations(d);
    	} else {
    		performCalculations(d);
    	}
    }
