Infinity

The Math.min() function works like Math.max(), but returns the smallest of the arguments. Called with no arguments, it returns Infinity.

For arrays you also need the spread syntax: Math.min(...prices).

It’s often used to cap a value from above, for example so a progress bar doesn’t exceed 100%: Math.min(progress, 100).

Math.min(value1, value2, …)

Parameter	Type	Description
value1…valueN	numbers	The values being compared.

Widely available

Works in all modern browsers, phones included. You can use it without worry.

Very large arrays (hundreds of thousands of elements) can exceed a function’s argument limit. Use reduce() instead in that case.
Math.min(value, 100) is a simple way to set an upper limit.
