javascript calculates the product from 1 to 10

Use a for loop to traverse the numbers from 1 to 10 and multiply them to obtain The product of 1 to 10.

for (var i = 1; i <= 10; i++) {
cj *= i;
//或
//cj = cj * i;
}

The variable cj is used to obtain the final product value. In order not to affect the result when defining, it needs to be initialized and assigned the value 1.

var cj=1;

The variable cj is defined before the for loop.

The complete implementation code is given below:

var cj = 1;
for (var i = 1; i <= 10; i++) {
	cj = cj * i;
}
console.log("1到10的乘积为：" + cj);

Encapsulated into a function:

function cj(n) {
	var cj=1; 
	for (var i=1;i<=n;i++){
		cj *= i;
	}
	return cj;
}
console.log("1到10的乘积为："+cj(10));
