javascript - I am taking user input and splitting it - how to best check types for each and also remove spaces? -

-

i'm not sure if there's better way this.

basically, taking user inputs example - hair salon, 1, 4

when split , ['hair salon',' 1',' 4']. doing error check make sure 3 values passed max, how can remove spaces (' 4') , check 'hair salon' string, , other 2 numbers?

thanks

suppose have user input 

hair salon, 1, 4

now split(','), array

var arr = ['hair salon', '1','4']

you every input string 

for(i=0;i<arr.length;i++) {  arr[i] = arr[i].trim() // remove space & front }

in case needed data type of inputs, can check using 

typeof (arr[i])) - in loop

hope, suffice need
