Javascript Float64Array fill()

Introduction

The Javascript Float64Array fill() method fills values into a typed array.

This method works the same as Array.prototype.fill(). 

Float64Array.fill(value[, start = 0[, end = this.length]])
Parameter Optional Meaning
value Required Value to fill the typed array with.
startOptional.Start index. Defaults to 0.
end Optional.End index (not included). Defaults to this.length.

If start is negative, it is treated as array.length+start.

If end is negative, it is treated as array.length+end. 

let a = new Float64Array([1, 2, 3]).fill(4);     
console.log(a);//from ww w  .  jav a 2  s  .c  o m
a = new Float64Array([1, 2, 3]).fill(4, 1);      
console.log(a);
a = new Float64Array([1, 2, 3]).fill(4, 1, 2);   
console.log(a);
a = new Float64Array([1, 2, 3]).fill(4, 1, 1);   
console.log(a);
a = new Float64Array([1, 2, 3]).fill(4, -3, -2); 
console.log(a);
