# Inequality in value and type in JavaScript

In addition to the `!=` operator, there is also the `!==` operator, which takes type into account when comparing. Let's look at the differences between them with examples.

Let the operator `!=` compare two numbers `3`. This operator compares values to the fact that they are NOT equal. Since our values are just the same, the condition will be false:

`if (3 != 3) { console.log('+++'); } else { console.log('---'); // it will work }`

Now let one of our values be in quotes. In this case, the operator `!=` will still consider them equal (since the value is the same, and the type is not important for this operator) and again the condition will be false:

`if ('3' != 3) { console.log('+++'); } else { console.log('---'); // it will work }`

Let's now compare the two numbers `3` using the operator `!==`. He will also consider them equal:

`if (3 !== 3) { console.log('+++'); } else { console.log('---'); // it will work }`

But if we now quote one of the threes, then the operator `!==` will consider them unequal, since, although their values are the same, they have a different type:

`if ('3' !== 3) { console.log('+++'); // it will work } else { console.log('---'); }`

Without running the code, determine what will be output to the console:

`let test1 = '3'; let test2 = '3'; if (test1 != test2) { console.log('+++'); } else { console.log('---'); }`

Without running the code, determine what will be output to the console:

`let test1 = '3'; let test2 = '3'; if (test1 !== test2) { console.log('+++'); } else { console.log('---'); }`

Without running the code, determine what will be output to the console:

`let test1 = 3; let test2 = '3'; if (test1 != test2) { console.log('+++'); } else { console.log('---'); }`

Without running the code, determine what will be output to the console:

`let test1 = 3; let test2 = '3'; if (test1 !== test2) { console.log('+++'); } else { console.log('---'); }`

Without running the code, determine what will be output to the console:

`let test1 = 3; let test2 = 2; if (test1 !== test2) { console.log('+++'); } else { console.log('---'); }`
