Variables	Flux variables hold values. A variable can only hold values defined by its type.	flux_v0_ref parent name Flux specification Variables	104	/influxdb/v2/reference/flux/language/variables/ /influxdb/cloud/reference/flux/language/variables/	/flux/v0/get-started/syntax-basics/#variables, Flux syntax basics - assign variables

A variable represents a storage location for a single value. Variables are immutable. Once a variable is given a value, it holds that value for the remainder of its lifetime.

Any Flux type can be assigned to a variable. Use the assignment operator (=) to assign a value to a variable identifier.

var1 = "string value"
var2 = 1234
var3 = {firstname: "John", lastname: "Doe"}
