What is the maximum statement in javascript?
The Math.max () function returns the maximum value in a set of numbers.
Grammar
Math.max (value1 [, value2,...])
Parameters.
Value1, value2,...
A set of values
Return value
Returns the maximum value in a given set of numbers. If at least one of the given parameters cannot be converted to a number, NaN is returned.
Description
Because max is a static method of Math, you should use Math.max () rather than the method of the created Math instance (Math is not a constructor).
If there are no parameters, the result is-Infinity.
If any parameter cannot be converted to a numeric value, the result is NaN.
Example
Use Math.max ()
Math.max (10,20); / / 20Math.max (- 10,-20); / /-10Math.max (- 10,20); / / 20
The following method uses the apply method to find the largest element in a numeric array. GetMaxOfArray is equivalent to Math.max, but you can use getMaxOfArray () to act on arrays of any length.
Function getMaxOfArray (numArray) {return Math.max.apply (null, numArray);}
Or it is easier to get the maximum value in the array by using the latest extension statement spread operator.
