Terminal printando in yellow

Question

Hello, I am learning Javascript and in my terminal, when I run some code, some prints come out in yellow. Does anyone know why ? Thanks.

const peso1 = 1.0
const peso2 = Number('2.0')
const peso3 = 1.1
console.log(peso1, peso2)  
console.log(Number.isInteger(peso1))
console.log(Number.isInteger(peso2))
console.log(Number.isInteger(peso3))
const avaliacao1 = 9.871
const avaliacao2 = 6.871
const total = avaliacao1 * peso1 + avaliacao2 * peso2
const media = total/ (peso1+peso2)
console.log(media)
console.log (media.toFixed(2))
console.log(media.toString())
console.log(media.toString(2))
console.log(typeof media)

The colors are to differentiate strings from other types (such as boolean and numbers). In the CMD of your print the strings appear blank.

In browsers there is also color differentiation. In the prints below, I changed the line const peso1 = 1.0 for const peso1 = "1.0" (1.0 as a string, just to illustrate):

Chrome

Firefox

In Edge there is no distinction of types (and colors). That’s why he grouped the 3 values 23.15:
