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
RESCRIPT
let forEachU: (int, int, int => unit) => unit
forEach
RESCRIPT
let forEach: (int, int, int => unit) => unit
forEach(start, finish, action)
equivalent to Belt.Array.forEach(Belt.Array.range(start, finish), action))
Examples
RESCRIPTBelt.Range.forEach(0, 4, (i) => Js.log(i))
// Prints:
// 0
// 1
// 2
// 3
// 4
everyU
RESCRIPT
let everyU: (int, int, int => bool) => bool
every
RESCRIPT
let every: (int, int, int => bool) => bool
every(start, finish, p)
equivalent to Belt.Array.every(Belt.Array.range(start, finish), p)
Examples
RESCRIPTBelt.Range.every(0, 4, (i) => i < 5) /* true */
Belt.Range.every(0, 4, (i) => i < 4) /* false */
everyByU
RESCRIPT
let everyByU: (int, int, ~step: int, int => bool) => bool
everyBy
RESCRIPT
let everyBy: (int, int, ~step: int, int => bool) => bool
everyBy(start, finish, ~step, p)
. See Belt.Array.rangeBy
, equivalent to
Belt.Array.every(Belt.Array.rangeBy(start, finish, ~step), p)
Examples
RESCRIPTBelt.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
RESCRIPT
let someU: (int, int, int => bool) => bool
some
RESCRIPT
let some: (int, int, int => bool) => bool
some(start, finish, p)
equivalent to Belt.Array.some(Belt.Array.range(start, finish), p)
Examples
RESCRIPTBelt.Range.some(0, 4, (i) => i > 5) /* false */
Belt.Range.some(0, 4, (i) => i > 2) /* true */
someByU
RESCRIPT
let someByU: (int, int, ~step: int, int => bool) => bool
someBy
RESCRIPT
let someBy: (int, int, ~step: int, int => bool) => bool
