# Checking the characters of a string in JavaScript

Let some string consisting of digits be given:

`let str = '12345';`

Let's check if the first character of this string is equal to the number `1`:

`let str = '12345'; if (str[0] == 1) { console.log('!'); }`

Let's now check the last character for equality to the number `5`:

`let str = '12345'; let last = str[str.length - 1]; if (last == 5) { console.log('!'); }`

Given a variable containing some string. Check that this string starts with character `'a'`.

Given a variable containing some string. Check that this string ends with the character `'x'`.

Given a variable containing some string. Check that this string starts with the character `'a'` or the character `'b'`.
