how to return to be output for mutlidimention array in FUNCTION

Question

can multidimensions array return in function to display the all value in the 2dimentions array ??

function display(arr) {


}

const result = display([
["str", 1],
["str2", 2],
["str3", 3]
])

const result2 = display([
["str", 1],
["str2", 2],
["str3", 3],
["str4", 4]
])

const result3 = display([
["str", 1],
["str2", 2]
])

console.log(result)
console.log(result2)
console.log(result3)

i know console.log might work, how about return it in function ?

the output i want it // str = 1, str2 = 2, str3 = 3 // str = 1, str2 = 2, str3 = 3 , str4 = 4 // str = 1, str2 = 2

return arr.map(([str, value]) => str + " = " + value).join(", "); — ibrahim mahrir

BTW, you should let display handle the logging itself, so instead of returning a string that you need to log yourself later, just call console.log directly inside display. Unless of course you want to use the resulting string elsewhere. — ibrahim mahrir

This work for your code :

function display(arr) {
    return arr.map((key) => `${key[0]} = ${key[1]}`)
}

const result = display([
["str", 1],
["str2", 2],
["str3", 3]
]).join(', ')

// result = "str = 1, str2 = 2, str3 = 3"
