Recently, while learning JavaScript ES6, I came across a strange result of -infinity on my console when running the following code:
let numeros = [1, 5, 10, 20, 100, 234];
let max = Math.max.apply(numeros);
console.log(max);What does this -infinity value signify?
Thank you
When using the Function#apply method, it's important to note that the first argument should be thisArg. If you pass the array as thisArg, it essentially calls Math#max without any arguments.
According to the MDN docs:
If no arguments are given, the result is -Infinity.
To resolve this issue, make sure to set Math or null as the thisArg.
let max = Math.max.apply(Math, numeros);
let numeros = [1, 5, 10, 20, 100, 234];
let max = Math.max.apply(Math, numeros);
console.log(max);As pointed out by @FelixKling, starting from ES6 you can utilize spread syntax for providing arguments.
Math.max(...numeros)
let numeros = [1, 5, 10, 20, 100, 234];
let max = Math.max(...numeros);
console.log(max);Opt for using the ES6 Spread operator instead:
let numbers = [1, 5, 10, 20, 100, 234];
let maximum = Math.max(...numbers);
console.log(maximum);As noted by @Pranav C Balan, the return value of -Infinity is specified by the Math.max() function when no arguments are provided:
