Range
A small utility module to provide inclusive range operations for [start,
finish]. Internally it is relying on loops instead of creating new arrays,
which makes it pretty performant and memory friendly.
forEachU
let forEachU: (int, int, (. int) => unit) => unit
forEach
let forEach: (int, int, int => unit) => unit
forEach(start, finish, action)
equivalent to Belt.Array.(forEach(range(start, finish), action))
RESBelt.Range.forEach(0, 4, (i) => Js.log(i))
/*
* prints:
* 0
* 1
* 2
* 3
* 4
*/
everyU
let everyU: (int, int, (. int) => bool) => bool
every
let every: (int, int, int => bool) => bool
every(start, finish, p)
equivalent to Belt.Array.(every(range(start, finish), p))
RESBelt.Range.every(0, 4, (i) => i < 5) /* true */
Belt.Range.every(0, 4, (i) => i < 4) /* false */
everyByU
let everyByU: (int, int, ~step: int, (. int) => bool) => bool
everyBy
let everyBy: (int, int, ~step: int, int => bool) => bool
everyBy(start, finish, ~step, p)
See Belt_Array.rangeBy
equivalent to Belt.Array.(every(rangeBy(start, finish, ~step), p))
RESBelt.Range.everyBy(0, 4, ~step=1, (i) => mod(i, 2) === 0) /* false */
Belt.Range.everyBy(0, 4, ~step=2, (i) => mod(i, 2) === 0) /* true */
someU
let someU: (int, int, (. int) => bool) => bool
some
let some: (int, int, int => bool) => bool
some(start, finish, p)
equivalent to Belt.Array.(some(range(start, finish), p))
RESBelt.Range.some(0, 4, (i) => i > 5) /* false */
Belt.Range.some(0, 4, (i) => i > 2) /* true */
someByU
let someByU: (int, int, ~step: int, (. int) => bool) => bool
someBy
let someBy: (int, int, ~step: int, int => bool) => bool
someBy(start, finish, ~step, p)
See Belt_Array.rangeBy
equivalent to Belt.Array.(some(rangeBy(start, finish, ~step), p))
RESBelt.Range.someBy(1, 5, ~step=2, (i) => mod(i, 2) === 0) /* false */
Belt.Range.someBy(0, 4, ~step=2, (i) => mod(i, 2) === 0) /* true */
