Suppose we have the variable str
that stores some arbitrary string:
let str = '12345';
Let's write a condition that will print a message to the console if the length of the string is equal to or greater than three characters:
let str = '12345';
if (str.length >= 3) {
console.log('!');
}
The variable arr
contains some
array with numbers. Write a condition
that checks that there are 3
elements in the array. If so, print
the sum of the array elements.
