My current node version is 12.22.6.
I'm struggling to understand why this code isn't working correctly.
It seems like I must be missing an important basic concept, but I can't quite pinpoint it.
const changeVars = (variable) => {
console.log(variable + " is a " + typeof(variable) + "\n");
}
const myVariables = [
42,
"42",
{number: 42},
{},
true,
undefined
]
myVariables.forEach(variable => changeVars(variable));
node vars.js
$ SyntaxError: Unexpected token 'var'
Avoid using reserved words to name your variables as it can result in errors. Make sure to check the full list of reserved words here.
Examples of reserved words include:
break
case
catch
class
const
continue
debugger
default
delete
do
else
export
extends
finally
for
function
if
import
in
instanceof
new
return
super
switch
this
throw
try
typeof
var
void
while
with
yield
Always ensure that your variables do not share the same names as reserved words to avoid conflicts.
let is an essential term in javascript. Consider using a different variable name.
Avoid naming your variable var since it is a reserved keyword in JavaScript.
(On a different note: I suggest using camel-case for variables; for example, changeVars instead of change_vars)
let is also a reserved keyword in JavaScript, so you'll need to choose a different name for your variable: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Lexical_grammar#keywords
