A boolean is a data type with two possible values:true (1) or false (0). The two values help represent truth conditions found in logic control structures. The name comes from a branch of mathematics calledBoolea
Notice that this type definition does not provide any semantic information on what the types represent. It doesn’t tell us anything about why theTinArray<T>, and theTthat is the first input to the function are the same, it only tells us that they must be the same. It doesn’t ...

At a depth greater than or equal to eight, TypeScript compiles your code but no longer type checks it. For example, the following code assigns a number to a string property but does not cause a compilation error because the referenced property is at a depth of 10: myColl.findOne({ 'be...
