Eager evaluation

In computer programming, eager evaluation, also known as strict evaluation or greedy evaluation, is the evaluation strategy used by most traditional programming languages. In eager evaluation, an expression is evaluated as soon as it is bound to a variable. An opposite alternative to eager evaluation is lazy evaluation, where expressions are evaluated only when a dependent expression is evaluated depending upon a defined evaluation strategy.
