Returns true if all elements of a sequence satisfy a condition.

Usage

Test if all the numbers 0, 1, and 2, are less than 3 like this:

var all = require('@kingjs/linq.all');
var sequence = require('@kingjs/enumerable.create');

var enumerable = sequence(0, 1, 2);

all.call(enumerable,
  function(o) { return o < 3; }
);

result:

true

API

declare function all(
  this: Enumerable,
  predicate?: (x) => boolean
): boolean

Interfaces

Parameters

• this: A sequence of values.
