Math.min()
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The Math.min() static method returns the smallest of the numbers given as input parameters, or Infinity if there are no parameters.
Try it
console.log(Math.min(2, 3, 1));
// Expected output: 1
console.log(Math.min(-2, -3, -1));
// Expected output: -3
const array1 = [2, 3, 1];
console.log(Math.min(...array1));
// Expected output: 1
Syntax
Math.min()
Math.min(value1)
Math.min(value1, value2)
Math.min(value1, value2, /* …, */ valueN)
Parameters
value1, …,valueN-
Zero or more numbers among which the lowest value will be selected and returned.
Return value
Description
Because min() is a static method of Math, you always use it as Math.min(), rather than as a method of a Math object you created (Math is not a constructor).
Math.min.length is 2, which weakly signals that it's designed to handle at least two parameters.
Examples
Using Math.min()
This finds the min of x and y and assigns it to z:
const x = 10;
const y = -20;
const z = Math.min(x, y); // -20
Clipping a value with Math.min()
Math.min() is often used to clip a value so that it is always less than or
equal to a boundary. For instance, this
let x = f(foo);
if (x > boundary) {
x = boundary;
}
may be written as this
const x = Math.min(f(foo), boundary);
Math.max() can be used in a similar way to clip a value at the other end.
