(Reverse) Polish Notation in JavaScript

There was a time when I despised JavaScript. True story. But things have changed much since. What I like about modern JS is its versatility and ease of use. It has a relatively simple syntax, making it accessible to developers with varying levels of experience.

Consider a common problem used during programming teaching courses: the Polish Notation (and Reverse Polish Notation, too). Polish notation (PN), also known as normal Polish notation (NPN), Łukasiewicz notation, Warsaw notation, Polish prefix notation or simply prefix notation, is a mathematical notation in which operators precede their operands, in contrast to the more common infix notation, in which operators are placed between operands, as well as reverse Polish notation (RPN), in which operators follow their operands. PN and RPN do not need any parentheses as long as each operator has a fixed number of operands. The description “Polish” refers to the nationality of logician Jan Łukasiewicz, who invented Polish notation in 1924.

KEDS Essays — Applying 1 Corinthians in Church Ministry Today

Discuss how Paul’s teaching on ministry by women in 1 Corinthians should be applied in today’s church.


How do Pauline teachings in First Corinthians impact the ministry and role of women in today’s church life? Are women permitted to be in positions of authority and leadership, such as pastoring, preaching and teaching? The matter is debated today more than it ever was in the past (Laney, 2002, p. 8), and scholars are divided in two broad categories: complementarians and egalitarians. Both sides claim scriptural support for their positions, therefore the different conclusions must be determined by exegetical differences, presuppositions, the role of textual criticism, and the understanding of the Sitz im Leben, amongst other factors.

We shall begin by describing each side’s general stance, looking at foundational verses. We shall then carry out comparative exegesis of relevant texts. Finally, we shall determine the applicability of such texts to modern day church as we come to our own conclusions regarding women’s role in ministry.
