function exhaustive(): TOutput; Example type Permission = 'editor' | 'viewer'; type Plan = 'basic' | 'pro'; const fn = (org: Plan, user: Permission) => match([org, user]) .with(['basic', 'viewer'], () => {}) .with(['basic', 'editor'], () => {}) .with(['pro',...
All a hash function does is turn a value into an array index. The hash function in turn is composed of two parts.The first part, the hash code, takes a value and returns an integer. A function that always returned zero would be a hash coding function, but it would be a terrible ...
Searchesstringfor the first substring matching the regular expressionregexp, and returns an integer giving the position of this substring counting from1. If it finds no such substring,matchreturns zero. This function also sets the built-in variable RSTART toposand the built-in variable RLENGTH to...
