What are square brackets used for in coding?
Square brackets in programming languages Brackets are used in many computer programming languages, primarily for array indexing. But they are also used to denote general tuples, sets and other structures, just as in mathematics.

What do brackets mean in ARM?
register indirect
with “brackets” (register indirect) loads r0 with the value whose address is stored in r1 — in other words, if r1 holds 1000, r0 will be loaded from MEM[1000]
What do square brackets mean in API documentation?

Dear parenthesis, I am an angular square bracket with a passion for punctuation. If you share my feelings, please get in touch (my number is [587] 286-9901). This is not a hard and fast rule though. For instance, in the sciences, some formulas that use parentheses may need to go inside square brackets.
